Figure 3From: RIDDLE: reflective diffusion and local extension reveal functional associations for unannotated gene sets via proximity in a gene networkLocal extension (LE) adds functionally associated genes to increase the overlap between two gene sets. (a) Local extension is particularly useful when a weakly significant overlap between a query gene set and a known functional set is detected by a classic enrichment method. (b) The positions of the genes in a global functional network are consulted. (c) Close network neighbors are added to one set, and the significance of the newly formed overlap is re-calculated.Back to article page
