Dear Tiago,
I used G.purge_vertices(in_place=True). But the vertex filter didn't work.
G.set_vertex_filter(prop=exist) G.purge_vertices(in_place=True)
gt.graph_draw(G, pos=pos) # step 1 largest component in network A UA = gt.GraphView(G, vfilt=v_type)
line 45：LCA = gt.label_largest_component(UA) exist.a = False for v in G.vertices(): if LCA[v]: exist[v] = True for n in v.all_neighbours(): if not v_type[n]: exist[v] = True
G.set_vertex_filter(exist) G.purge_vertices(in_place=True)

This seems to be something else. Could you please provide a full working example, so I can investigate? Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
