Hi Tiago, thank you for the response! I've tried what you said, but I'm still a little stuck. I don't know how to incorporate the group numbers of ng into the loop and associate them with the vertices of g, so all I end up with currently is a dictionary of vertices (and their labels) in the largest component. Here's the code I have. Any help would be greatly appreciated! import graph_tool.all as gt, collections from pylab import * g=gt.load_graph("network.xml") name = g.vertex_properties['_graphml_vertex_id'] g = gt.GraphView(g, vfilt=gt.label_largest_component(g)) spins = gt.community_structure(g, 1000, 100) ng = gt.condensation_graph(g, spins) gt.graphviz_draw(ng[0], overlap=False, output="network.pdf") groups = collections.defaultdict(list) for v in g.vertices(): groups[name[v]].append(v) for a,b in groups.iteritems(): print a,b On Sat, Aug 11, 2012 at 9:28 PM, Tiago Peixoto [via Main discussion list for the graph-tool project] <ml-node+s982480n4024769h81@n3.nabble.com>wrote:

condensation graph documentation. For example, I have a graph in GraphML that I import with the vertex property "_graphml_vertex_id", from which I follow the rest of the example posted in the documentation to produce a condensation graph.
However, I want to see which vertices end up being grouped together. How would one go about reversing the condensation graph to see the groupings? I apologise if my question is silly, I'm still very new to graph-tool, which I think is a remarkable piece of work (thank you!). All you have to do is search for vertices with a specific value of the property map. You can do this by looping:
groups = defaultdict(list) for v in g.vertices(): groups[vertex_id[v]].append(v)
# now 'groups' is a dictionary with all the vertices for each group
You can also search for individual groups by using the find_vertex() function:

I hope it helps.
Cheers, Tiago
