categories in which relationship among genes is not defined, relationship among genes in a network module is well-defined by the network graph. To reveal this additional level of information, WebGestalt uses the Cytoscape Web (25) plug in to visualize in a network graph the input genes (in green) and their direct neighbors (in white) in the enriched modules (Figure 2B). For enriched KEGG pathways and WikiPathways, WebGestalt has implemented methods to call APIs provided by corresponding resources to view the pathway maps and highlight input genes in the maps (Figure 2C).
