 All right, so welcome everybody. Welcome to the NF Core Hackathon. It is a great pleasure to have you all on board this week for our first ever fully online hackathon. And during this week, there will actually be two parallel events taking place, the next flow tutorial and the NF Core Hackathon. And if it hadn't been for the pandemic situation, these events would have taken place in Heidelberg and had been co-organized by the German Cancer Research Center in Heidelberg and the Quantitative Biology Center in Tübingen. And that's why they kindly sponsored the next flow tutorial that is going on also this week. However, we are glad that this event could still take place online. And we are very excited to see that it attracted even more participants than ever. So let's have a look at what awaits us this week. The next flow tutorial already started this morning and it will take place from 9.30 to 11.30 during the rest of this week. The NF Core Hackathon will start after this talks and will continue non-stop until Friday. Of course, it's scheduled from 9 to 5 p.m. in the Central European Summer Time as most organizers are in this time zone, but you can contribute at any time depending on your time zone and availability. Every day at 1 p.m., there will also be some interesting talks on relevant NF Core and bioinformatics topics. Today, we start with an introduction to NF Core and a tutorial on how to run NF Core pipelines. On Tuesday, we will have a glimpse of the latest developments on next flow DSL2 and modules and how they will be incorporated into NF Core. On Wednesday, we'll have a talk by Ellen Cronander, an invited speaker on data management solutions for bioinformatic projects. And on Thursday, we'll have a talk about the latest updates in NF Core tools and guidelines. And finally on Friday, we'll present you three featured NF Core pipelines in detail, the RNA SIG pipeline, viral recon and Sarek for variant calling. And we'll talk about what do these pipelines comprise and how can you use them for your research. After the talks, we'll do a daily wrap up to present what has been going on during each day of the hackathon and to make sure we are all up to date into the latest hackathon developments. So how can you join the hackathon talks? You can join them via Zoom and this has the advantage that you can then participate into the live Q&A session and all the hackathon talks will also be live streamed on YouTube and be available later on demand. To find the links to join us on Zoom or on YouTube, you can just go to the NF Core website to the events page and in the Hackathon July 2020 event, you will find all the information that you need to join all the sessions. On Thursday, additionally, we'll have a virtual social event which will comprise an online pub quiz via Kahoot and for the interested ones, virtual escape room afterwards. So join us on Zoom for this social event and you can test your NF Core and next flow knowledge in the pub quiz. And in this event, we will also be able to get to know each other a bit better and talking about this, who will actually be at the hackathon. So for the first time, this hackathon is fully online and currently there are more than 100 people registered and we are very glad that making this event fully virtual has attracted people from all over the world, from Cote d'Ivoire to New Zealand, from US to South Africa and in many different countries in Europe. When it comes to the next flow level of all the participants, we have participants from all the different levels, so from never tried running next flow before to written several pipelines. So don't be afraid of asking questions and participating even if you're a beginner. If you're stuck somewhere, just ask some questions and surely someone can help you answer those. When it comes to the experience of writing NF Core pipelines, we are also glad to see that there about half the participants are new to the NF Core community. So this is a great opportunity to get started. And especially for the NF Core newbies, you can stay for the talks today where Phil Iwls will talk about what is NF Core and how to join us. And Frederica Hansen will hold a tutorial on how to run NF Core pipelines. But so what will we be working on during the hackathon? We've asked you already in the registration form which topics you would be interested about and checking your answers. We've come up to with four hackathon projects, project to work on new pipelines, a project to work on existing pipelines on improving them, a project to work on the DSL2 template and DSL2 modules for NF Core. And finally, a project to work on improving the current NF Core tools which are written in Python. So originally there was also a fifth project, the AWS mega test, but this will be merged with the NF Core tools to have a balanced amount of people per project. So how can you participate in this hackathon project? For each of the projects, there's a Slack channel in our NF Core Slack. So you can just join us on Slack and add yourself to this channel. There will be also a jitzy room where you can video call with all the other hackathonians that are participated in your same project. And we will also track the progress via hackMD slides. You can add the progress that you have been done into your slides and then we will present them during the daily wrap ups. And finally, we also have a hackathon project board on GitHub. So just have a look there and there are some issues and pull requests collected which can give you an idea on what to work on during this week. And if you try and add also the PRs and issues that you're currently working on there, it helps us track the progress of the hackathon. So that could be all from my side. We will follow up now with the talks of Phil and Federica, but if you have any questions, please write them now in the chat and I'll try to answer them.
