Co-occurrence network of genes in Liverome. Shown here is a matrix representation of the co-occurrence network, where genes are represented on rows and columns in the same order. Elements in the matrix are color coded according to the similarity between corresponding pairs of genes. Genes that are grouped into modules are indicated by the color bars and by the associated clustering trees. Blocks along the diagonal indicate that the genes in the same module are more interconnected than those between modules. Details on the plot can be found in the documentation of the WGCNA package. The enriched biological pathways for selected modules are also shown. The modules are numbered as indicated in Additional File 4.
