[graph-tool] About extract communities from a graph

After using community_structure(), each vertex in the graph has a community property. However, how to extract some certain communities from this graph ? Such as, the graph G contains communities {1,2,3,4,5}, now, I hope to get and save a sub-graph which contains the vertices and their edge in communities {2,4,5} of G ? Is there any continent and fast function or algorithm in graph_tool to solve this problem ? -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
