Main Topological Parameters of the Transcriptional Silencing Network

No. of nodes	34
No. of edges	75
Clustering coefficient	0.037
Diameter	5
Average number of neighbors	2.574
Characteristic path length	4.294

The number of nodes represents the total number of molecules involved; the number of edges represents the total number of interactions found; the clustering coefficient is calculated as CI = 2nI/k(k – 1),where nI is the number of links connecting the kI neighbors of node I to each other; the network diameter is the largest distance between two nodes; the average number of neighbors represents the mean number of connections of each node; and the characteristic path length gives the expected distance between two connected nodes.
