Network Properties of KEGG and STRING.

The ‘Total Nodes’ column contains the total number of nodes available in the network while the ‘Gene (Protein) Nodes’ column shows the number of nodes with at least one gene in KEGG (or one protein in STIRING). The fourth and fifth columns contain the total number of edges, and the number of connected components having at least one gene (or protein), respectively. ‘Avg. Node Degree’ represents the number of edges a node has on average. ‘Max Node Degree’ denotes the maximum number of edges a node has in the network. ‘Clustering Coefficient’ is the ratio of the triangles to the connected triples in a graph.
