 specific interaction networks. I've worked in protein interaction networks for many years and I've seen many of those databases and papers producing what they claim to be specific networks. These are networks that are either tissue specific or disease specific but they all make the same way. They take a global network such as string and they remove the proteins that are not expressed in the tissue or disease of interest. The positive view on this is that if you take such a network inquiry for a protein you will get likely interactors in the specific tissue or specific disease of interest. That is genuinely useful. The negative view is that the interactions themselves are not in any way specific. This is a filtered global network. It's not a specific network and calling it that is therefore simply misleading. I'd love to hear your opinion on that in the comments.
