Network parameters in STRING

Network parameters	Source: 2 channels Confidence Score = 0.4	Source: 2 channels Confidence Score = 0.9	Source: 1 channel (Exp) Confidence score = 0.4	Source: 1 channel (Exp) Confidence score = 0.9
Interactions	3502	1385	359	52
Number of connected nodes	204	173	91	Collapsed network with three clusters of 28 nodes
Average node degree	34.3	13.6	3.52	0.51
Average local clustering coefficient	0.652	0.542	0.283	0.163

An average node degree is a numerical value of how many interactions (at the score threshold) a protein has on the average in the network. The clustering coefficient is a measure of how connected the nodes in the network are. 2 channels denote data retrieved from experimentally proven data channel as well as databases and text mining channel

Exp stands for experimental channel only
