 If you haven't, hello, hello, starting our stream Monday moody Monday This stream was brought to you by advanced biomaterial braiding Work with polymers three What's resorbable resorbable polymers metal wires To develop low profile solution Yeah, I'm not allowed to I don't even know what it is. I'm not allowed to click on my On ads displayed on my website. So So if you haven't checked the barnicales.com, please go do so. There is a lot of interesting tools one of the more recent ones is this ECG game needed to record a video to go at the bottom of the page Don't have a good one. We might just do it now. So this tool Scrolls the different ECG waveforms on the screen and you meant to click on which one is abnormal. So if you see some abnormality in the A pq rst A click on it That's how you gain scores and in the newer version you play against the robot I mean, you're not really playing against that. We can collaborate because the robot will actually tell you everything it does It's a fuzzy logic algorithm lost looking at positive peaks negative peaks row amplitude A R peak sharpness. So it's essentially halfway through the epic looking at the distance on the left and right And the intervals between P and R and R and T so between the different peaks even the pq rst And we'll give you an abnormality score. So in this case, it's high meaning it's likely to be abnormal Point seven so it's between zero and one point five still point five five is still on the high side Point seven so you know to click on it if you just look at that number there You can kind of collaborate with the robot and this one has a point three nine or point three And that's on the lower side And that tells you it's a normal signal. So do not click on it And yes, some are harder to detect than others can also reduce the noise Then And see how it affects the normal the robot. Well, and your own performance Yeah, for normal ECG it goes Normal abnormality score goes all the way down to point two eight something Yeah, we know for sure the robot doesn't make any mistakes whatsoever when the noise Is low like this And you shouldn't make any mistakes either unless you are not paying attention Which is very common for humans. Unfortunately Now when we send the noise all the way up It will start making mistakes in this case The false alarm rate will go up It keeps false alarming. So essentially It's labeling essentially everything as abnormal You can try and fix the algorithm, but it's actually good for you to see what happens We've increased noise that some of the A algorithms even the fancy fanciest machine learning algorithms. They just stop working So if you wonder why this is a good tool to explain that to show that in Well real world, but yeah, this is synthetic data, but Yeah, we simulate All these possibilities. So you can see the false alarm for the robot keeps going up And actually now as a human I probably have a chance to match the Score Of the machine Yeah, because it will keep making mistakes. So in theory its score Should be going down and still going up Well, right because um Yeah, there is a bias in the system. There is 60 40 60 percent Abnormal and only 40 percent normal A waves coming from so if if you just keep clicking on everything Your score will be going up And yeah, it's it is much harder Yeah, that was normal and it becomes much faster as you gain 50 scores and more Three started for a sec Yeah, so that's the default Noise level and we'll be doing some mistakes. No, hopefully not too many the robot And you if you paying attention should be fairly straightforward with this noise level To detect which one Which way for me is abnormal Yeah, and as you saw when it reaches 50 points, um the speed increases slightly And they have videos of me reaching thousand points. That's crazy fast So beware Can obviously go try it out on bionicchaos.com And yes, they are ads running. So apologies in advance Hopefully get something relevant We'll be also adding this, uh, hopefully not too annoying tool where you can Select the number of particles and the speed of them And there's this little drum in the middle where when we Each time a particle bounces Against that it will generate a sound the sound is importantly actually this description is wrong I have to rewrite it Yeah, GPT started like hallucinating with a Code it generated by itself In terms of uh, there's a few Incorrect things about it. And yes, we have a disclaimer for GPT for and github copilot use That will be on the side Should be everywhere really on the side Here's a structured disclaimer and some thoughts on the future applications of this tool in biomedical engineering and medical data analysis disclaimer This particle motion simulation tool was developed with assistance from ai technologies including open ai's gpt 4 and github copilot These ai systems provided guidance and suggestions during the coding process However, it's important to note that while ai contributes significantly the final implementation design decisions and responsibility for the codes functionality and performance lie with the human developers The ai systems are tools to augment the development process not replacements for human creativity and decision making future directions Biomedical engineering applications one simulation of biological systems The principles used in this particle simulation can be adapted to model complex biological systems like blood flow in vessels Or cellular interactions in various environments 2 Customized prosthesis design ai can assist in the design of prosthetics or orthopedic implants by simulating how they interact with the human body Leading to more personalized and efficient designs 3 drug delivery systems Simulating the behavior of nanoparticles or other carriers in the human body can optimize the delivery of drugs to target tissues Improving efficiency and reducing side effects medical data analysis and review 1 Predictive analytics using ai to analyze medical data can help in predicting disease trends Patient outcomes and treatment efficacy leading to more informed decision-making and Just talking rubbish We Yeah, the prompt wasn't great Yeah, I don't think we have to update that code might update the code for a sec It would be nice to tie this to eag actually Have different channels the number of particle for each channel Yeah, that's what I was trying to get at not the general stuff Yes, we actually can use that way. I don't I do actually have a gear Which I can record eag. Let me know If I should Undust it Try it again It might be a while to set up. It's a bit prototypy But yes, you can have your number of channels and the speed could correspond to frequency which No, it doesn't at the moment The sound that being generated Is corresponding to the So first of all each particle is its own note Yeah, I tried different note scales currently we're using supposedly I think it's wrong D major so notes between D4 and C5 And there is a Not the correct amount. So some of the notes, you know, as you keep adding them, I think we'll get the repeated The speed is currently just set manually as you could tie it to eag or something Yeah, so eag review doesn't have to be this, you know, old school Stuff like this We want to Develop some newer ways To review eag yes, so even though it's Time series data can review it in a different way. It's safe to be So as you scroll through the file as more eag coming in, you can just update that This tool is a bit heavy. You can hear my cpu Yeah, and it has an error in it as well. It's loading In a certain way and then the css the styling is applied after like 10 20 Yeah 20 seconds or so Which is not great Yeah, this is a more kind of standard eag review You can group by left and right or overlay them all Which can be useful in this case. You only have a 16 Yeah, the separation one work in this case A group by side Yes, operation one work as well. So it works for off And then you can decide what your separation level is This is a seizure Yeah, an evolution of a seizure And then quiet after the seizure ends And this is 60 implanted channels that are available in the public domain Available on igie eag.org In just a simple registration and you cut yourself the data There was an older kegel competition using that data Anyways, I'm just saying you could convert something like this To to that Essentially when you have a seizure the frequency goes up. So then the speed Can go up like that So you can essentially see and hear The seizure in a different way We to have a tool that allows you to listen to seizure And eag to musical better But yes Someone someone was saying that it's not Not real essentially. Yeah, but there is some fancy not fancy, but there is a remapping to musical To musical notes And that's therefore To as special as this might sound a bit odd Because normally they don't do this Remapping to music. They just keep it at the frequencies So for example, if I'm playing four notes I'll be just doing These exact frequencies converting them directly to sound But it sounds horrible. So It's okay to review for a couple seconds, but you won't be Actually sitting there listening to it when you have to review very long a period periods of time Yeah, so Still testing this one and hopefully it will be you can make it available for you to play with and watch more ads On this side Um, yeah, I'll just add the more description. There's some this currently wrong It's actually to rewrite the description Are we using that disclaimer? Yeah, I need to change it a bit Uh, this is how we use co-pilot for simple sim. It's good for a simple task A convert text to html It's good at doing those specific things human developer The labels instruction for users Yeah, we need a h2 label In there It's not completing the right that sounds legit. What else we got? Yeah, those feature directions are Not right It's not a lot shit Hey, this is also wrong So I can't read I have to use the board This is a simple particle motion simulation with collision sounds The particles are created using javascript in the canvas element The particles are given a random velocity and direction and then updated every frame When a particle collides with the edge of the canvas it plays a collision sound The number of particles and the speed of the simulation can be adjusted using the controls Yes, this is not quite right that description is not quite right Let's just load the javascript in it and add html Yeah, we just add this Hey, can we write a detailed overview of this web application Can we also write? one paragraph on how to use it Also, finally, can we write another paragraph on future directions? For example How can we use a tool a visualization tool like this? for reviewing EEG data that for example might have epileptic seizures Overview of the web application This web application is an interactive particle simulation designed to demonstrate physics principles and sound synthesis in a visually engaging manner The application utilizes html 5 css and javascript with the core functionality embedded within a javascript file At the heart of the application are two main classes stationary circle and particle Stationary circle creates static circles used here to define the central stationary circle and the boundary circle The particle class represents the moving elements within these circles Each moving with a set speed and colliding with the boundaries and each other key features one canvas visualization The html 5 canvas element is the stage where particles move and interact two Dynamic particle system users can adjust the number of particles and their speed through sliders affecting the system's dynamics in real time three Collision physics the particles exhibit realistic behaviors upon collisions including bouncing off each other and the circular boundaries four sound synthesis unique to this application Each particle collision produces a sound with the pitch linked to the particle's assigned frequency and the volume related to the collision's velocity five interactive controls Users can interact with the system using sliders for particle count and speed plus a button to restart the simulation Six visual and auditory feedback the simulation provides a combined audio visual experience Where changes in the system dynamics are immediately visible and audible How to use the application To use this web application you'll interact with a canvas displaying moving particles within a circular boundary Adjust the number of particles and their speed using the provided sliders As the particles move and collide they generate sounds based on their velocities and predefined frequencies If you want to reset the simulation with new settings just hit the restart simulation button This application is user friendly and requires no advanced knowledge to interact with and enjoy the physics and sound synthesis demonstration Future directions data visualization and analysis Envisioning future directions this particle simulation framework could be adapted for more complex and meaningful applications Such as visualizing and analyzing EEG electroencephalography data particularly in the context of neurological conditions like epilepsy For instance imagine using a similar particle system where each particle represents a different EEG data point or channel Movements and collisions of particles could correspond to different brainwave patterns with the color or size of particles indicating abnormalities like epileptic spikes or seizures This could provide a dynamic real-time representation of brain activity making it easier for researchers and clinicians to identify and analyze patterns associated with epileptic seizures Moreover integrating sound synthesis could add another dimension to the analysis Different frequencies or sound patterns could be linked to specific types of brainwaves or seizure activities Providing an auditory cue to complement the visual representation This multisensory approach could enhance the understanding and interpretation of complex EEG data Offering a novel tool for diagnosis research and even patient education about their neurological conditions Really good. I couldn't have written anything better myself. That's for sure So the board is winning again So we have a disclaimer already that we are using AI technology for both Generating the code and writing the text So currently it's on the prototype. Yeah, by the way Yeah, obviously this tool is very prototyped. This is just developed in one day yesterday Yeah, GPT4 actually did a better job at generating the code A co-pilot seemed to be silly. Sometimes it seemed to Pretend not to understand the context or something of what is it you're trying to do That seemed to be really good at like writing a specific line of code, but I'm not sure how good it is with text Yeah, I'm pretty sure this It's mentioning the classes. So it's pretty detailed and it will be more A updated as well Hey, we'll keep the disclaimer for pilot Convert text to html format now like now. What is it? Doing this is not cool Yeah, the implementation of the LLM is Absolutely crucial Can you convert this text into html? Right, this is more like it. I don't know when you use the control i It's probably looking at the other code as well. I don't know why Yeah, there might be a bit of a confusion of when sound is being actually generated But again, that's a prototype so we can change it later at the moment It's only generating when the particles hit that drum in the middle, but Yeah, I'm not sure what's in the text, but we can change it later I think it just keeps it generic at this stage actually So if you're reviewing a EEG with something like this That can be just circling In a specific direction Well, obviously a clock clockwise So it will be like your EEG clock or something Should we call it EEG clock? Yeah, so all these tools are quite prototyping at the moment Yeah, there is always a question of How much more do you need to you know develop it improve it? Before it's considered less prototyping I would say never it's everything is a prototype even though It's called a product A lot of products are prototypes you can look at the Windows Even look at the Nvidia GPUs for example Yeah, for example now I'm having lots of trouble with drivers for Linux. I mean it's working, but then there's A You know 10 different types supposedly optimized for various things, but it's not clear seem to be all A again prototypy And you have ones that have all this like new features and that stuff But supposedly less stable. So this is what this is They still sell it as a product you can That Nvidia software thing that does eye tracking essentially replace on you if you can see The eyes are there Still testing the tool it is available on the side That's an option to Split the view And yeah, and then they just Eyes that look at the camera. So it looks like you You know talking with the audience whatever A that tool is Very raw to say the least I have some older Videos on it Testing it out. It's only works on Windows. I think so now I'm on Linux. I kind of and use it anymore But even on Windows. Yeah, it was a Yeah, pretty And yes, it's supposedly free, but then you have you need the You know an expensive a GPU to actually run that software. So no it is not free so, yeah question Fair enough, but I don't think anyone can really answer it. What's a prototype and what's What's an actual product? It's working really really well. I haven't tried it on now a machine though No questions like how many resources does it take currently? And so this is running all in the javascript. There's no back end at the moment Yeah, if you add some eg Data for this it will require a back end See how we go that this one does have a back end pretty sure Is this where the data is being pulled from sitting on the server? So yeah, go check out those tools And you will be supporting the project that way as my The other thing following from the same question. It's a prototype or not Is I don't even know how many users I can support? So currently I'm streaming so using a lot of resources that way But yes, I don't even know how many users I can support with this. So if You know all of um, I don't know how many 10 users will go on the side together. It's using my actual CPU So yeah, if you probably shouldn't give you any hints, but if you want to crush my stream So the card you bought for example if I close this page Not much Changed One of the cpu was used. I think I'm limiting each flat complication to a one or two cpu's stream is using I think variable frame rate So when there's actually something a lot of something going on on the screen The network use will probably go up So if it's actually Hey, it works that way or not Yeah, there's a network more network usage That's why that's probably for using this tool. I am using it through um Like Through the web at the moment. I should be really testing it locally when I do this But I do want to kind of see what is it you would see Close this for a sec Yeah, we use that description already. We'll be publishing this one Lee How about we just do it now It's actually meant to be that doing this gaggle a competition, but I know this won't bug me if I don't publish it It's working pretty well. What's the web page called? not card you bought I will have a plan out one too A That's more of a blog Yes, someone was asking about it. Yeah, it looks like this at the moment. This actually has the cause is kind of Yes, it's just a blog those are static Images the basic one in the more realistic blend almond blend altman plot and it's actually Has this sample python code in it that use that was used to generate these two Charts You can just copy paste it essentially general overview on the plots essentially publishing of Of them or maybe that one is already Published That's already it's already live. Ah, it's missing the images Yeah, we can Check the images and it's already running as that's not good That's not good Oops microphone is muted Microphone's mute is not good as I was saying need to redeploy The website and I forgot how to do it To about last week or so It should be And in for in for text file Or just search for deploy looks like it We uh We're not releasing a new flask application. Hopefully we'll do one this week Later this week. So I don't think we need to Restart like you can do it. Yeah, let's say deploy first the website will go It will go down for a few seconds Like 10 seconds or so Should be back and the plan altman. Yeah, now it's better So that's what should look like. Yeah, this disclaimer obviously we can do better with this disclaimer More like More a bit more extensive Yeah, we had an old A particle motion to don't worry about We need to do a patchy conflict test Oops a syntax. Okay. Do we need to restart a patch? I don't think so won't be restarting it now because the website will go down again. We don't really need that Don't really need that Yes, if you interested in land almond plots There is a link and this one should be live as well I forgot what's called particle something particle Yeah, it's called particles too Is it the large like that? What does it look like? It's scaling nicely It's actually pretty pretty nice Don't remember Don't remember actually doing What does it look like on a mobile? Yeah, this thing is not fun. Um, so the browser is essentially preventing a preventing a music from playing What font do you have? It's it's not always accurate. So I know so I have my custom A dimensions Yeah, the theoretical Dimensions of the phone is not actually the actual dimensions Yeah, it's confusing like that Yeah, it will scale quite nicely. I like it Did it load the Add I don't think so Yeah, the audio So you need to essentially interact with the page for the audio to kick in Why so big like that? Yeah, we need the It should be so huge Should limit the Stasis The canvas and it's cool back This did local again This works. No, no one knows. No, I'm sorry. I don't know someone is Screaming at me For not using it correctly. Yeah, don't get it. Yeah, they meant to be delay The delay doesn't work really well. Yeah, I'm loading the page Actually meant to be doing this caggle caggle competition today And yeah, I'm just trying to fix the size of this thing. It's like gin almost I don't like it obviously It's okay to scale horizontally. I don't get it. It's scaling fine on mobile This is mobile. Anyway, I'll leave it like this for For now hopefully it's not as bad as this one Yeah, we'll add those to the Yeah, that label is wrong. That label is wrong Anyway, let's move on quickly Yes, we have a tool called seizure buzz Because we applying fuzzy logic to seizures We actually have now our git is working better Yeah, let's actually open it and the new window Yeah, this one. So this is the caggle competition It's uh, I mean this is loading data format trying to display it Let's run Okay, this is what the front page looks like. You know, why it's so small It will fix a little bit You can yeah, that one doesn't work well You can select your It's called a eg id. That's just how the data is stored. It's a really weird format sexual competition There's 22 more days to go. We don't worry about it We worry about the data. So we have the 26.5 gigabyte It's stored in this weird fashion. We're trying to display it So currently we're loading the spectrum data, but it's not actually updating To the corresponding eg id. So we need to fix that Then we be doing some basic processing and training a fuzzy logic algorithm do A classification. So I have a bunch of labels in this data And specifically Those with different type types of abnormal eg activity Let's get to let's look at the data quickly. Yeah, that's what we have In the data and mostly the most Important file currently is this train csv Can open it look what's unit essentially There is an eg id So this one already works in that too It pulls out the corresponding And you see that there are multiple copies of it And that there is an offset in seconds So for example, the original one that we load by default has this 18 Labels I know they're all the same anyway, and that's interesting 42516 Yeah, the patient said six of four and said Table pivot table should we do a pivot table? I'll do it based on say expert consensus Yeah, we don't care, but Well, really the expert consensus is the only useful thing in it That should be fine Okay, that was wrong So we haven't selected that correctly. I'll re-modify the pivot table Okay, we don't want a mess around with these too much We just do a regular table You can freeze first row that's handy Let's just add a regular table like in excel Yeah, freezing first row is handy anyway Um, we have a six of four That should be somewhere in the beginning now That's interesting. This one has 90 sub-ids. It's quite unusual And it's starting to chat quickly Keep saying quickly, forever quickly, is it? It's been the slowest It's okay So we have a this is a flasked application Should already actually be published as well Hey, that's the structure The data Yeah, two more about the info Can do the front page Let's see it should give a summary All right, I see you've got a screenshot of an EEG electroencephalogram data viewer And it looks like it's part of a web application for visualizing EEG data It's displaying a segment of EEG data with an indication of a seizure event from the electrode placement Fp1 The graph shows typical seizure activity with a significant spike in the EEG readings Which is common during such neurological events The interface seems user-friendly with drop-down menus for selecting different EEG IDs Expert consensus, which in this case is marked as seizure And other parameters like EEG sub-ID Electrode and patient ID The chart below the selection options is a visual representation of the EEG readings from the selected electrode Which can help medical professionals or researchers to analyze the brain's electrical activity Also the source reference at the bottom points to a data set from a competition on Kaggle Suggesting that this tool could be used for a machine learning or data analysis project focused on classifying harmful brain activity The code snippets included are parts of what seems to be a flask application used to serve this EEG data visualization tool It shows javascript for client-side interactivity and python for server-side data handling, which is typical for web applications For a detailed exploration, I'd typically run the code But in this context it appears to be only a part of the larger application However, it gives a good idea of how the application is structured and operates It fetches data, populates drop-downs, displays a chart and a spectrogram based on the EEG data And handles user interactions to update the visualizations accordingly The python flask app is the back end here Serving the data and managing the routes for the various API calls made by the front end Someone's asking saying I'm interested in data analytics Do you have suggestions what I should learn first? Well first first of all You should go and check it out by honeycares.com Because that of course will answer all your questions No, I'm just joking, but Yeah, if you do check the website and you have any specific questions That are relevant to one of the tools We're actually publishing more tools as we speak To let me know No, so you could probably do this A machine learning data analytics competition. It's on Kegel. So already We trying currently just to load Load the data Just proven to be a bit hard because it's organized in a weird in a weird fashion But yeah, we have that 26.4 gigabyte of data And it is Solid in this way. So currently we have Why did the bot say that the code is not Complete? Don't think it's read it correctly I think it's read all that So we have back end in here and front end because the data is in the back end The data is in this park at the raw data is in this park at while so obviously Python can happily Deal with them pass them Do whatever you need with them So that's good Yeah, that's very sick Are we getting some errors? No, they're all 200 So that's good Okay, so I have the eg id have different types of eg It looks like potentially spiking. It's actually says the lpd. lpd is one of the labels. We have one two three four five six labels. We have experts A labeling this data Let's look at the data on different eg channels You have the patient id hopefully it's correct. I'm not actually sure this is a back and Bing Hey, this is what we're doing last time So the spectrogram is now displayed Are we always displaying the same spectrogram? All the answer to that should be yes What it's not always the same spectrum is displayed determine Spectrogram IDs used to look at a corresponding parquet file Okay We selected different eg id Can we print out the Spectrogram ID is Okay, spectrum ID is 10 8 3 What happens if we select? Okay, how about when selecting a different eg id Do we also have the updated spectrogram id from the test csv file the answer to that should be no Yeah, it does not update automatically blah blah blah Yeah, we do want to we do need to update that Actually need to not just print it in the back and we We might want to display it on the on the front page Create a map between eg id and spectrum ID Well, how come you don't know where it is? We have get the spectrogram data We haven't changed anything in the code, but It might get rid of this silly comments I wonder if people start the Coding without any comments considering A most language models can explain Most code these days Let us start convert H that Write this one. Yeah, that's a default Don't do that. Just get rid of The comment because again, we'll just have the gpt or co-pilot Explaining the code Yeah, we'll leave that one this assembling rate So I have this chower script Can we explain how the spectrum id Is being found from the train csv file? How is it being updated when the eg id Is changed on the front page? A currently we seem to have with the displaying the same spectrogram regardless of what Of when the eg id is changed by the user Yep, sure, let's break it down step by step How the spectrogram is fetched and displayed One fetching Sure, let's break it down step by step How the spectrogram is fetched and displayed One fetching the spectrogram data The function fetch and display spectrogram spectrogram id is called with a spectrogram id It sends a get request to the server side flashgap at the root slash get spectrogram data slash int spectrogram id Which is expected to return json data for the given spectrogram id Two server side handling on the server the get spectrogram data spectrogram id function handles the request It attempts to locate a file named spectrogram id dot parquet within the train spectrogram's directory If it exists it reads the parquet file into a panda's data frame and then converts it to json format before sending it back to the client Three displaying the spectrogram Once the json data is returned to the fetch and display spectrogram function on the client side It calls display spectrogram spectrogram data This function is responsible for drawing the spectrogram on a canvas element It iterates over the frequency data and maps intensity values to grayscale colors Filling in each cell of the canvas to represent the spectrogram visually How the spectrogram id is found The spectrogram id isn't directly fetched from the train dot csv file within the provided javascript code Normally you'd expect a function that upon changing the eeg id in the dropdown would look up the corresponding spectrogram id in train dot csv And then call fetch and display spectrogram with the new id However, the code you've provided seems to hardcode the spectrogram id fetch and display spectrogram 64651083 so it doesn't change based on user interaction Updating the spectrogram When the eeg id is changed to update the spectrogram when the eeg id is changed by the user You would need to add functionality that one detects a change in the eeg id via an event listener Which you already have set up for other elements Two looks up the related spectrogram id from the train dot csv data based on the selected eeg id Three calls fetch and display spectrogram with the new spectrogram id to fetch and display the new data Current limitation currently as mentioned above the code does not update the spectrogram based on the eeg id selected by the user It always displays the same spectrogram because the spectrogram id is hardcoded Solution to address this you would add a function to fetch the related spectrogram id whenever the eeg id is changed This function would one fetch the related data from the server, which includes the spectrogram id Two update the client side state with the new spectrogram id Three call fetch and display spectrogram with the new id This would likely require an additional endpoint on the server to provide the mapping from eeg id's to spectrogram id's Or could be done by adding the spectrogram id to the related data fetched with the slash get related data endpoint You would then update the event listener for the eeg id drop down to call this new function when the selection changes Um, okay. Why don't you generate the function? Can you actually generate the necessary code? So that the spectrogram is displayed correctly Making sure It's a retrieving the spectrogram id From the test csv that corresponds to the currently selected eeg id A train csv, that's right It's amazing how it gets all the context correctly It can correct human mistakes Yeah, probably humans will be making way more mistakes than the bots I'm pretty sure we already have this In a JavaScript code as we do eeg id this value. Yeah, we get the eeg id This one's the same. I don't why you regenerating it Okay fetch update chat And update charge and fetch spectrogram id and update. Okay, this is the The new function to fetch and display the spectrogram Okay, that comment is obviously just for me Don't need it in the code and here is the actual function Data populate drop down Data display initial data fetch Fetch and update that chat. Okay, we can do it over here somewhere Add a new root to get the spectrogram id for a given eeg id from train.csv Okay, now Python code At the This root Are we adding a new one? How many routes routes routes routes We currently have 10 why so many Have cat patient id get related data It's a weird one should have been just I don't think we need this one Get spectrogram data And this one is getting the spectrogram id Please note that the new root get underscore spectrogram underscore id less than int eeg underscore id greater than will fetch the first spectrogram id associated with the given eeg id This is based on the assumption that train.csv has a spectrogram underscore id column corresponding to each eeg underscore id If train.csv has multiple rows with the same eeg underscore id This will only fetch the spectrogram id of the first one If you have a different logic for selecting which spectrogram id to use you'll need to modify the code accordingly In case it's working, okay the first time around When you select a different eeg id It's giving an error because like doesn't exist or what Hey, we're getting the following error Just to be sure the first time around The spectrogram is loading and I assume it's the correct one Because you obviously passed The train csv file correctly But then again, I'm getting an error. So when selecting a different eg id Um Something is not right. Can you check the code and update? Yep Is a better voice. The error you're encountering when changing the eeg id get slash get spectrogram id Slash 3284507976 Htp 1.1500 dash indicates that there's a server side issue in the flask route that is supposed to fetch the spectrogram id The 500 htp status code means there's an internal server error This is likely because the route is trying to access a spectrogram id that doesn't exist Or there is an issue with how the data is being accessed in the data frame Let's revise the slash get spectrogram id slash int eeg id endpoint to handle cases where the eeg id does not have a corresponding Spectrogram id in the train dot csv. Here's the updated server side flask route to handle this case Python at app dot route slash get spectrogram id in eg id Def get spectrogram id e-guide try df equals pd dot read csv opath dot path train dot csv Check if the eg id exists in the data frame and retrieve the first instance if it does if eg id and df e dot values Related data equals df eg id equals eg id return jsonify spectrogram id related data spectrogram d Else return an appropriate message if the eg id is not found return jsonify error eg id not found 404 accept exception as e return the actual error message for debugging return jsonify error star e 500 With this change if an eg id that doesn't exist is requested The server will return a 404 error with an eg id not found message instead of a 500 server error This will help you diagnose issues on the client side as the client should handle this case For example by not attempting to display a spectrogram if the id is not found Now let's also add a check on the client side javascript to handle the case when the spectrogram id is not found Javascript function fetch spectrogram id and update eg id fetch slash get spectrogram id slash eg id Then response equals if response dot ok throw new error failed to fetch spectrogram id Status return response dot json Then data equal if data dot spectrogram id fetch and display spectrogram data dot spectrogram id Else console dot error no spectrogram id found for the given eg id eg id Handle case where spectrogram id is not found clear the canvas or display a message Decatch error console dot error error This updated function will now log an error message if the spectrogram id is not found And you can add additional UI handling as needed such as clearing the spectrogram display or showing an error message to the user Yeah, I wasn't actually listening but hopefully that code just works. I mean it's a simple And something simple that doesn't work So this is in a byte Yeah, just the error error handling there So that's good And in javascript we have a fetch spectrogram id and update Just going to be displaying that Error on the Yeah that console Error Let's try it out. So the first time we run it. There's no errors when we select a different eg id The reason error We have a team It's failing to fetch the A spectrogram id. Yeah I should have an example of Yeah, the trend csv Can you focus on this one Here's an example of the train csv file A first 23 entries again. We already shared it before A can you fix the code? I'm getting the error above The first time around it's working. Okay, and we're displaying a assuming Correct the spectrogram to begin with but when selecting a different eg id Something doesn't work. Can you fix that? Yep It looks like the server route that fetches the spectrogram id for a given eg id is failing Resulting in a 500 internal server error To fix this we should adjust the slash get spectrogram id eg id route to correctly handle cases when a corresponding spectrogram id is not found in the train csv file Additionally, we need to make sure that the flask server is not encountering any other issues that would cause an internal server error Here's the corrected flask route slash get spectrogram id into eg id python at app dot route slash get spectrogram id slash into eg id What's reading the code the text to speech The one I have in building the browser doesn't so what did it actually change? so I might just edit more Error handling I imagine Return the spectrogram underscore id associated with the first entry for the eg underscore id If the eg underscore id is not found it returns a 404 not found status with a helpful message Log the exception and return a 500 internal server error status if any other error occurs This error handling will ensure that the flask route properly communicates for when wrong to the client side making debugging much easier The int spectrogram underscore id is used to ensure the json serialization doesn't encounter issues with data types After adjusting the flask route ensure that the client side javascript can handle different server responses correctly In particular make sure the fetch spectrogram id and update handles the case when the server responds with a 404 not found status Indicating that there's no spectrogram underscore id for the selected eg underscore id Here is an example It's just sorry. So this this voice obviously not as good as the one from open ai But I have more control over it. Yes, we reviewed the client side It's clear that when we get the spectrogram data it is weird but it is there however The question is what happens if we select a different eg id and it doesn't work Okay, so it didn't just do more Error handling. It's actually fixed the code So that's good So now that the thing about it so again this code is from this Kaggle competition from Harvard medical school harmful brain activity classification and blah blah blah There's prize money. It's the last thing for another 22 days But that should be plenty to win it if you are a machine learning specialist Which I'm not so if anyone wants to team up for this one More than happy to to do so because I do have Some experience with the g data So currently we do have the 26.5 gigabyte downloaded on a server. It's open access a data set In here by default when loading the pages loading this eg id reason being It has something that looks like a seizure or what we used to a process on another project Can check how it looks like on different eg journals can check the ecg and this one is weird because If you want this scaling correctly to have anything in styles css called style or normally called styles with plural shouldn't matter but As long as it matches in html it actually Check if it's working a sorry just check if By the way, there's a problem with patient id and not loading correctly It's obviously gpt4 is better in html Before We display the spectrogram We would like to display the spectrogram id, but we might as well do it over here We don't need that silly comment patient id in here It's display spectro id That's actually interesting that that's suggesting that because It is what we are having the train csve file Vg label No way to say that's actually wrong You're really displaying there No, we don't need to submit We have the offset in seconds display a spectrogram and the Spectrogram label offset in seconds What the label id actually means nid for the patient who donated the data that's patient id label id nid for this nid for this set of labels What does making sense? but Okay, let's do one at a time Yeah, I'll need some explanation for this html page as well Before we publish the tool and make it available for you Yeah, the code is not super large. So we It's like medium size. I added some a new Outputs in the html specifically the spectrogram id and the spectrogram label offset in seconds. I would like to actually populate them The spectrogram id we should already have from the back end We just want to display it on the front panel of what this should correspond to the current A spectrogram that being displayed on the screen And it should update as well when a different eeg id is selected Now each spectrogram also has the label offset in seconds And we need to figure out how to display it as well Can you prototype something and update the code By the way in the side note we're streaming on the link the in YouTube facebook and twitch On twitch we always have like one viewer and on youtube we have a couple And a couple more on linkedin A facebook is nothing because I just started using facebook as well But this is kind of low Priority by the way if you want to go A live as well we can bring you live Using zoom if you don't like using the the text chat in any of the platforms Can let me know i can bring you up on zoom you can also talk about what is it you are doing And if you haven't checked bionic chaos yet, please do so There is a lot of tools that You might be interested in at least one of them i'm sure And don't forget to let me know what you think Apparently we're also adding a bunch of new ones in a search It doesn't really work but you can To remember the names I haven't actually put i'll put links to them on the on the front page Yeah, we have a bunch of we actually have a privacy page You need it for the advertisement thing We also have A particles I was actually I know it kind of just looks silly and Not relevant but actually Later we would be Trying turning this into a different way to review eeg Wayforms so for example if you had a sieges like we Do have say in this example Then the speed could be mapped to frequency each channel has its own note A musical note The number of particles will be the number of channels you have 20 20 of them So you will have 20 particles like this And once you Having a seizure so if this was Showing this data over time so you will see all the channels And if there is a seizure During seizure it will start going like this and then slow down again After the seizure We can have each channel like in a different color or A different musical note which we currently have So this is just a prototype for something like that Which is also available on the site, but there's no link to it on the front page yet Then there's also A another type of someone was asking about it actually Yeah, we do like ads like that that are relevant to medical field It's a blend the altman plot And this is just a blog. It's not a dynamic. It's just a static page Which is not ideal, but that's where we start from and then you have this example so Blend altman plot And you also have the actual code python code that used to generate these two images And yes gpt was used Need to expand on that disclaimer wants to join in You can set up a zoom room. I'll put it in a chat if you just want to jump live that's And talk in real time In this case potentially we'll go there Review seizures in a more in a different way And You could map Speed to frequency Yeah, I have to think about how to do it exactly Yeah, I have to check how is this How the spectrograms Um actually being displayed might be something wrong Yeah, those are not images. Those are parker files. I'm still not displaying the Spectrogram ID Yeah, kind of trust the GPT-4 better GPT-4 Yeah To accomplish the tasks you described, we will need to update both the flask back end and the javascript front end Flask back end First let's update the flask back end to serve the necessary data for the new drop downs We will modify the slash get related data route to include spectrogram id and spectrogram label offset seconds python at app dot route slash get related data def get related data EEG ID equals request dot args dot get EEG ID Sub ID equals request dot args dot get sub ID. If not EEG ID or not sub ID return jsonify error missing EEG ID or sub ID 400 try df equals pd dot reads csv os dot path train dot csv related data equals df df d ID dfs of db equal int sub ID I lock zero return jsonify expert consensus related day consensus patient ID int related data Spectrogram ID int related data spectrum ID spectrogram label offset seconds int related data Spectrogram label offset seconds accept exception as e return jsonify error star e 500 Next let's update the javascript to populate the new drop downs and handle the updates when the EEG ID changes First modify the update related data function to populate the spectrogram ID and spectrogram label offset seconds drop downs Javascript function update related data EEG ID sub ID if EEG ID and sub ID fetch get related data EEG ID and sub it so Then response equals if response dot okay return response dot json else throw new error failed to fetch related data Dot data document get element expert consensus value equals data dot expert consensus Document get element by ID patient ID values data dot patient ID document get element by ID Okay, okay, okay. It's just I don't know why it's even reading The whole code spit odd We updated get related data in the front and Okay updates related data and it takes EEG ID and sub ID as input that sounds legit Hopefully the IDs are correct Can actually Test in a second Is it correct? It is it's not being updated You may need to create additional drop downs or displays for the new data as well Here is an example of how to populate a drop down Do have it why do I need a Finally call this function within the update related data function after fetching the data With these changes when a different EEG ID is selected the spectrogram ID and spectrogram label offset seconds drop downs Will update to show the correct values corresponding to the currently displayed spectrogram Remember to call the function to update the child display after updating the drop downs to ensure that the display is in sync with the selected data A spectrogram ID drop down is currently not showing anything And not updating Anyone wants to join me live trying to share the zoom room pink for some reason having trouble Doing it Hey specifically on LinkedIn Okay, let's get back to it quickly We're trying to make this So this is data from this kegel competition Go check it out. If anyone wants to team up Hey, let me know as well. Just trying to display the Not the default one Is this EEG ID That seemed to have a seizure in it. You can't really see it in the spectrogram I'm wondering if there's something wrong with the way it's being plotted Those need to populate the spectrogram ID to make sure it's the correct one and the label offset because in this case There are 18 labels most of them overlap. So I don't know why there's so many a bit of a data budging there It's an example of how to load the normal size data set into big data It's just replicate a lot of the stuff Big GPT might have stuffed up a code I'm not certain it's been Yeah, I'm still in the java script. That is a problem with this bit It's shorter I'm pretty sure something would be missing This one was better. It was Actually displaying the spectrogram that spectrum is in the parquet files Have the structure for it. I don't think we're parsing it correctly should be four A of them So it's an example of the not example. This is the train csv It's kind of stuff we have in it All the labels as some example Yes, there should be four of these spectrograms But we get more than why Yeah, we're not parsing them correctly If anyone Wants to join live they discuss this A data set that the competition or whatever it's called. Yeah, she had my A zoom some reason. I'm not able to do it on In the linked and chat I just copy pasted from youtube Yeah, I should see the zoom A link in the chat It's with how linkedin works Okay, we still have the spectrogram ID Is not being displayed correctly. I think we can fix it in the code. That would be great Another thing we need to check Is that the spectrogram parquet file is being Passed correctly So it bothers a sample from the file And it's timing not matching the raw EG so the spectrogram is 10 minutes and the EG is 50 seconds or more Well, it should be 50 seconds. So we need to sort out how we display it all properly Yeah, the proper explanation of what the parquet file for the spectrogram is Yeah, this bit is important To display the spectrogram ID correctly and ensure the EEG and spectrogram data are in sync We need to adjust the code to fetch and display the appropriate spectrogram based on the EEG data timeframe First ensure the get related data route in your flask application is correctly returning the spectrogram ID and spectrogram label offset seconds This information will be used to fetch the correct spectrogram parquet file and display it Then you'll need to handle the timing difference between the EEG and spectrogram data Since the EEG data is over a different time frame than the spectrogram data You might want to display a specific segment of the spectrogram corresponding to the EEG time frame Here is the proposed approach to address the issue 1. Update the flask route to return additional information if needed For example, the length of time that the spectrogram data covers 2. In the front end use the spectrogram label offset seconds to determine which segment of the spectrogram to display If the EEG data covers 50 seconds Calculate the segment of the spectrogram data that aligns with the EEG data's time frame 3. Update the spectrogram display function to only display the relevant segment of the spectrogram Here's a snippet on how you might modify the spectrogram display function JavaScript Assuming the spectrogram is over 10 minutes 600 seconds and EEG data is 50 seconds function display spectrogram segment spectrogram data EEG duration Const canvas document get element by ID spectrogram canvas if canvas return const ctxels canvas dot get context 2d const canvas with canvas dot width const canvas height equals canvas dot height ctx dot clear rect zero canvas with canvas height calculate start To call this function you need to know the start time of the EEG data EEG start time and its duration the duration You'll have to fetch these details from the back end or calculate them based on user interactions Yeah, we do have data This is a high-level idea You will need to adjust the code to fit into your application logic ensuring that EEG start time and EEG duration are correctly calculated based on the EEG data being viewed Also, the back-end route might need to be adjusted to handle this logic and serve the right data segment The spectrogram files are stored in a parquet format, which is a columnar storage file format This means that each column of the data is stored separately allowing for efficient data compression and encoding schemes Parquet files are especially efficient for complex data structures because they support nested data such as lists and maps And because they allow for efficient data compression and decompression operations Here's an overview of how you might parse these files in a python flask application one Reading parquet files you can use libraries like pandas or pyaro to read parquet files in python These libraries support direct reading of parquet files into data frame objects Which are table like data structures similar to sequel tables or excel spreadsheets two Extracting data for display Once you have read the parquet file into a data frame you can process it to extract the necessary information for display If you're displaying a spectrogram, you'd be interested in columns that represent frequency bands for each electrode region lrl lp rp three serving to front-end After extracting and potentially processing the data like selecting a specific time range You'd convert the data frame to a json format that can be easily handled by the front-end for display This is often done using the t2 json method in pandas Which will serialize the data frame to a json string four Visualization on the front-end you would then take this json data and use it to plot the spectrogram using a javascript library That can render visualizations like chart.js or d3 js The json data would typically include time as one of the axes and the frequency intensity as the value to plot Let's break down the steps in more detail back-end flask application We focus on how the spectrogram parquet file is being passed and displayed and also make sure that the spectrogram id And the spectrogram label offset seconds are being retrieved from the train csv file correctly and displayed on the front page They're meant to be for spectrograms display as explained above All right, let's dive into how the spectrogram data is handled in your eeg data viewer application Retrieving and displaying spectrogram data your app deals with eeg spectrogram data in the following steps one fetching spectrogram id and label offset seconds The application retrieves the spectrogram id and spectrogram label offset seconds from the train.csv file These are retrieved through the slash get related data route which returns relevant data for a given eeg id and sub id The front end uses this information to populate the respective drop downs in the html two displaying spectrogram data The fetch and display spectrogram function requests the spectrogram data from the server using the slash get spectrogram data route with the spectrogram id The server returns the spectrogram data in a format that includes time and frequency intensity values The display spectrogram function then uses this data to create a visual representation of the spectrogram on the canvas element Analyzing the spectrogram data handling fetching and populating data The data flow seems efficient with each step logically following the previous However, the populate spectrogram id drop down function seems to be calling slash get related data Which could be redundant if the same endpoint is already used for populating other drop downs Consider optimizing this to reduce duplicate server calls visualization The visualization step is quite crucial The display spectrogram function takes the fetched data and visualizes it on a canvas The function processes the data into a grid where each cell represents the intensity at a given frequency at a specific time This is a good approach for visualizing frequency changes over time Handling of four spectrograms Your description mentions that there should be four spectrograms displayed corresponding to different recording regions ll rl lp rp However, it's not entirely clear from the provided code how these four different regions are being handled distinctly You might need to modify the display spectrogram function to handle these regions separately Or ensure that the data for these regions is distinctly fetched and visualized Room for enhancements the user interaction could be enhanced For example, it would be beneficial to have interactive elements on the spectrogram canvas Like tooltips showing frequency and intensity at specific points Error handling and user feedback can be improved For instance, notifying the user when no data is available for a selected combination or when there's an error fetching data Final thoughts Your current implementation seems to have a solid structure for retrieving and displaying EEG spectrogram data Focusing on handling the four different spectrogram regions distinctly and improving user interaction Would make your application more robust and user friendly Consider also looking into performance optimizations, especially related to data fetching and visualization rendering Update the yet underscore related underscore data route to fetch distinct spectrogram data for each region l l lp rp You might need to adjust the structure of the data in train.csv or how you query it to get these specific values In theory, we should have all this separate the canvases for The different spectrograms, which is how the raw data is being displayed It is some fundamental changes to the code So might lose what we Have so far Yeah, we're having a problem with parsing Yeah, let's display this a four separate canvases changing this place spectrogram And do we need to keep this one? Yeah, probably not I can cover that out We already have this function And now display spectrogram has the spectrum data and region age related data Yeah, we can comment this one And that one out Have get related data Hey, that will be enough python This will obviously not work F region not defined Which is fair enough May we have four of them And what else do we need to do? And the description And the regions are not defined Yeah, I suspect a GitHub co-pilot would not be able to deal with this Hey, we need to update this code Hey, I need you to help me the main problem Currently is that the spectrograms are not being displayed at all It looks like the primary issue is with the fetch and display spectrogram function Not correctly handling the region parameter This parameter needs to be defined And passed correctly to the display spectrogram function To ensure each region's spectrogram is displayed properly Here's how you can adjust the code to fix this One fix the fetch and display spectrogram function Modify the fetch and display spectrogram function To accept a second parameter region and ensure it is used correctly within the function JavaScript async function fetch and display spectrogram spectrogram id region Console.log fetching spectrogram for region region with id spectrogram id Try const response will wait fetch slash get spectrogram data slash spectrogram id If response dot okay throw new error network response was not okay Status code plus response dot status Const spectrogram data equals await response dot json Console.log fetched spectrogram data for region spectrogram data display spectrogram spectrogram data region Catch error console dot error error fetching spectrogram data error To update the display spectrogram function Modify the display spectrogram function to accept the region parameter and use it to target the correct canvas element JavaScript function display spectrogram spectrogram data region const canvas equals document to get element by id Real DIYs at reading the Code as well It sounds there The other text to speech tools do not do that Yeah, but we need to change It looks like the primary issue is with the fetch and display spectrogram function not correctly handling the region parameter This parameter needs to be defined and passed correctly to the display spectrogram function to ensure each region's spectrogram is displayed properly Here's how you can adjust the code to fix this And one sec just mute my back in a sec It looks like the primary issue is with the fetch and display spectrogram function not correctly handling the region parameter This parameter needs to be defined and passed correctly to the display spectrogram function to ensure each region's Spectrogram is displayed properly Here's how you can adjust the code to fix this One fix the fetch and display spectrogram function Modify the fetch and display spectrogram function to accept a second parameter region and ensure it is used correctly within the function JavaScript async function fetch and display spectrogram spectrogram id region Console.log fetching spectrogram for region region with id spectrogram id Try const response will wait fetch slash get spectrogram data slash spectrogram id If response dot okay throw new error network response was not okay status code plus response dot status const spectrogram data equals a wait response dot json Console.log fetched spectrogram data for region spectrogram data display spectrogram spectrogram data region Catch error console dot error error fetching spectrogram data error 2 update the display spectrogram function Modify the display spectrogram function to accept the region parameter and use it to target the correct canvas element JavaScript function display spectrogram spectrogram data region const canvas equals document that get element by id Spectrogram canvas style region if canvas console dot error canvas not found for region return const ctx equal canvas dot get context to d rest of the code 3 ensure html elements match make sure your html contains canvas elements with ids that match the format spectrogram canvas region where region is one of llrllp or rp html canvas id spectrogram canvas canvas canvas spectrogram canvas canvas xrogram includes spectrogram canvas rp 4 check backend data handling verify that your flask backend is correctly handling and providing spectrogram data for each region Ensure the data includes the required frequency and intensity information for each region 5 test and debug After making these changes test the application to see if the spectrograms are being displayed correctly Check the console for any errors and debug as needed by implementing these changes Your application should correctly fetch and display the spectrogram data for each specified region Ensure that the region identifiers llrllp rp are consistent across both the back end and front end Let's troubleshoot why the spectrograms aren't being displayed in your application Here are a few steps to take 1 check the network response open your browser's developer tools usually f12 and go to the network tab Trigger the fetch and display spectrogram function by changing the drop downs in your app Check if the requests to slash get spectrogram data int spectrogram id are successful and returning data If there's an error or no data, this could be the root of the problem 2 validate data format Ensure that the spectrogram data being returned from the flask app is in the correct format and contains the necessary information like frequencies and intensities for visualization 3 console logs You have console logs in fetch and display spectrogram Check the browser console for any logged messages or errors when fetching spectrogram data This could provide clues about what's going wrong 4 check canvas elements Ensure that the canvas elements for displaying the spectrogram are correctly defined in your html with the id's like spectrogram canvas lll Also, make sure these elements are properly sized and visible on the page 5 examine the display spectrogram function Verify that the display spectrogram function is being called with the correct parameters and that it's executing as expected A common issue could be that the canvas context isn't being used properly or the data isn't being mapped correctly to the visual elements 6 debug the display logic Temporarily add more console logs in the display spectrogram function to track how the data is being processed For instance, log the contents of spectrogram data canvas width canvas height cell width and cell height to ensure they are as expected 7 cross check with back-end data Make sure the data structure in the parquet files matches what your front-end expects If there's a mismatch it could lead to rendering issues 8 test with static data As a temporary measure try passing static data manually created data set resembling the spectrogram data format To display spectrogram to check if the issue is with the data fetching or with the rendering logic The logs and the behavior you're observing suggest that there's an issue with fetching related data for the spectrograms Checks if eg underscore id and sub underscore id are provided Handles the case where no data is Absolutely. Let's work on fixing the issue with your slash get related data route in flask and make sure it handles the requests properly Since I don't have access to your data set or the complete server log I'll guide you based on common practices and the information provided Fixing slash get related data endpoint Based on your description, it seems like there's an issue when the endpoint tries to access or process the data Here's a revised version of your endpoint with added error handling Python at app.route slash get related data def get related data eg id equals request dot args dot eg id sub id equals request dot args dot get sub id If not eg id or not sub id return jsonify error missing eg id or sub id 400 try df equals pd dot read cf os dot path data path train dot csv condition equals df

dot spectrogram id lp lp fetch and display spectrogram data dot spectrogram ID RP RP catch I understand the frustration and I'm here to help you get this sorted out let's tackle the issues with your code focusing on the problems with fetching and displaying the spectrogram data I'll guide you through the necessary updates one fixing the route for related data the get related data route seems to be failing when fetching data for a specific EEG ID and sub ID the issue might be with the way you're accessing the data from the data frame here's a revised version of the route Python at app route slash get related data def get related EEG ID equals request args.get EEG ID sub ID equals request args.get sub ID if not EEG ID or not sub ID return JSONify error missing EEG or sub ID 400 try equals

fetch and display spectrogram function ensure that the fetch and display spectrogram function correctly targets the right canvas based on the region here's the updated JavaScript function JavaScript async function fetch and display spectrogram spectrogram ID region console dot log fetching spectrogram for region region with ID dollar spectrogram ID try const response equals await fetch get

canvas console dot error canvas with ID canvas ID not found return rest of your drawing logic three ensuring proper error handling and logging make sure that all functions especially those fetching and processing data have proper error handling and logging this will help you diagnose issues faster for testing and verification test these changes to ensure that they address the problem pay close attention to the console logs and network requests in your browser's developer tools five further steps if the issue persists a more detailed inspection of your data structures especially how the dot parquet files are structured and how they're supposed to link with your EEG data would be necessary implement these changes and let's see how it goes if there's still an issue we'll dive deeper sure let's focus on the key areas where your code needs refinement to ensure the spectrogram data is correctly fetched and displayed one fetching spectrogram data your flask application should have the capability to fetch the correct spectrogram data the relevant route in flask seems correctly set up for slash get spectrogram data int spectrogram ID ensure that this route correctly reads and returns the spectrogram data to populating spectrogram drop downs when an EEG ID is selected you should fetch the related spectrogram IDs and populate the drop downs make sure the route get related data dot EEG ID EEG ID is working as expected it should return the IDs of the spectrograms related to the selected EEG ID three displaying spectrograms after the spectrogram IDs are fetched the corresponding spectrogram data should be displayed on the canvas your current implementation seems to be in the right direction but ensure that the data fetched from this from the server is correctly parsed and displayed on the canvas considering your setup here are the code snippets that need attention hash-flask route for fetching spectrogram data ensure this route correctly fetches and returns data from the dot-parket file python app route get spectrogram data slash int spectrogram ID def get spectrogram data spectrogram ID file path equals OS dot path dot join data path train spectrograms f
