The function chooses genes that are not found to be feature genes as enriched feature genes and assigns them into unique+shared feature gene sets
enrich_feature_set(so, min_edge_prop = 0.9)
SiFINeT object with enriched feature genes in geneset updated.
a SiFINeT object
minimum proportion of edges between a gene and a unique+shared feature gene set for the new feature to be assigned to the set
Genes that are not selected as feature genes would be added in the enriched section of the feature gene set if they are connected with more than min_edge_prop of the unique and shared feature genes in each of the feature gene group.
