Add TF activity as optional input to GRN
In addition to ATAC and RNA, TF activity can be added to the GRN framework. Let's summarize here the details so we can start thinking about how to do it, who does it and other details. @zaugg and @berest Could you quickly summarize what you had in mind?
In addition to TF expression (which is sample-specific, one value per sample), we then also have TF activity (which is specific for the pairwise comparison that we not integrate into the GRN framework at all currently, so only one value per TF). How would the link creation work then exactly?
