Hi everyone, I want to use the command “Graph.community\_edge\_betweenness()” in order to divide my network into sub networks. When I get the vertex weights by the command “Graph.edge\_betweenness()” and enter as weights in “Graph.community\_edge\_betweenness(weights=w)” for 2 clusters (condition1), there is not any differences in shown results with the results of condition that I do not enter weights(condition2) but, for 3 clusters, the shown clusters are different for both condition! So, first question is that how I can get the right weights for clusters more than 3 clusters and the second is that why these differences do appear? Thanks ---

It is unclear what you mean. Can you show a [complete minimal example](http://sscce.org/) that illustrates your question? ---

the first code is : import igraph g=igraph.Graph.Read(‘exp1.txt’, directed=False) d=g.community\_edge\_betweenness(clusters=3) p=d.as\_clustering() l=[(40,0), (10,10), (20,10), (30,10), (40,10), (50,10), (30,20), (40,20), (50,20), (30,30), (40,30)] igraph.plot(g,layout=l) the second is : import igraph g=igraph.Graph.Read(‘exp1.txt’, directed=False) w=g.edge\_betwenness() d=g.community\_edge\_betweenness(clusters=3, weights=w) p=d.as\_clustering() l=[(40,0), (10,10), (20,10), (30,10), (40,10), (50,10), (30,20), (40,20), (50,20), (30,30), (40,30)] igraph.plot(g,layout=l) But why there are differences between the shown communities(three clusters)? thanks ---

Can you make the example self-contained? We don’t have the data. Ideally, come up with a _minimal_ example that does not require an external data file.
