Schematic diagram of gene co-expression network analysis

Genes are clustered by their correlation of co-expression with other genes, resulting in gene modules shown in different colors. Within each gene module, nodes represent genes while edges represent correlations. The length of an edge is inversely proportional to the correlation of co-expression
