Hello!

How did this paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6372280/pdf/elife-41930.pdf) categorize the pathways in figure 2D (see below)? Are the categorizations of the pathways (Signaling, Immune Response, etc) determined by a particular package in R (GAGE itself?), or is it something the authors did manually? Thank you!
