Summary of 4 large heterogeneous biological networks for E. coli

Network	Nodes	Links	Node attribute(s)	Link attribute(s)
corr	4,454	4,408,269	gene name	WGCNA correlation weight
path	2,353	6,703	gene name	none
go	3,764	2,208,090	gene name	count and string of shared GO terms
ppi	2,042	3,888	gene name	source of evidence (Y2H, LIT or both)

Unconnected nodes and duplicate links have been removed from some of the networks. In all 4 networks, nodes are identified by gene names and differ in their link attributes
