Thanks, but the problem is that igraph doesn't even give the correct id mappings. it only gives the mapping of the structure(without labels)
For above eg: igraph only sees the one edge structure(of graph 2) without labels or names and gives all possible edges in the main graph(1) to be isomorphic to the query graph(2) On Wed, Aug 1, 2012 at 9:20 PM, Gábor Csárdi <csa...@rmki.kfki.hu> wrote: > Hi, > > igraph will give you the mappings via vertex ids.
