See https://web.archive.org/web/20080626113807/http://www.cs.purdue.edu/homes/koyuturk/pathway/ for a description. The summary is included here: A file that describes a uniquely labeled graph (with extension ".gr") format looks like the following: name 3 4 a 1 2 b c 0 2 "name" is simply a description of what the graph corresponds to. The second line displays the number of nodes and number of edges, respectively. This sample graph contains three nodes labeled "a", "b", and "c". The rest of the graph contains two lines for each node. The first line for a node contains the node label. After the declaration of the node label, the out-edges of that node in the graph are provided. For instance, "a" is linked to nodes 1 and 2, which are labeled "b" and "c", while the node labeled "b" has no outgoing edges. Observe that node labeled "c" has an outgoing edge to itself. Indeed, self-loops are allowed. Node index starts from 0. iÿÿÿÿN(tis_string_liket open_files s+Willem Ligtenberg (w.p.a.ligtenberg@tue.nl)s%Aric Hagberg (aric.hagberg@gmail.com)itmodetwsutf-8cCsó|jd|jj|ƒƒ|jd|jƒ|jƒfj|ƒƒt|ƒ}tt|tt |ƒƒƒƒ}xv|D]n}|jd|j|ƒƒx5|j |ƒD]$}|jd||j|ƒƒq­W|jdj|ƒƒq}WdS(s”Write NetworkX graph in p2g format.
