PCv12_pruned_igraph {PathwaySpace} | R Documentation |
A pruned and laid out igraph object from Pathway Commons V12.
Description
This igraph object was created from a 'sif' file available from the Pathway Commons V12 (Rodchenkov et al., 2020), which was filtered to keep interactions from the following sources: CTD, Recon, HumanCyc, DrugBank, MSigDB, DIP, BioGRID, IntAct, BIND, and PhosphoSite. The igraph was additionally pruned and laid out by a force-directed algorithm aiming signal projection on PathwaySpace's images. Edges with the smallest betweenness centrality were pruned using 'backward elimination' and 'forward selection' strategies. The resulting graph represents the main connected component with the minimum number of edges.
