Two versions of an E. Coli network dataset

Description

This network data set comprises two versions of a biological network in which the nodes are operons in Escherichia Coli and a directed edge from one node to another indicates that the first encodes the transcription factor that regulates the second.

Usage

1

Details

The network object ecoli1 is directed, with 423 nodes and 519 arcs. The object ecoli2 is an undirected version of the same network, in which all arcs are treated as edges and the five isolated nodes (which exhibit only self-regulation in ecoli1) are removed, leaving 418 nodes.
