Main topological parameters of capacitation and AR networks

	capacitation	AR
N°nodes	146	141
N°edges	197	191
Clustering coefficient	0.029	0.026
Diameter	20	20
Averaged n°neighbours	2.667	2.695
Char. path length	6.606	6.736

The number of nodes represent the total number of molecules involved, the number of edges represents the total number of interaction found, the clustering coefficient is calculated as CI = 2nI/k(k-1), where nI is the number of links connecting the kI neighbours of node I to each other, the network diameter is the largest distance between two nodes, the Averaged n°neighbours represent the mean number of connection of each node, the Char. path length gives the expected distance between two connected nodes.
