Hi Tiago, I'm working with some centrality measures provide by graph_tool and I have some questions: *Does the 'trust_map' parameter of the eigentrust centrality function refer to the edges' weight?* In the example present in the docs, it was used the edges' weight as value to 'trust_map', but in the parameters' description was said that this parameter refers to 'Edge property map with the values of trust associated with each edge. The values must lie in the range [0,1]." *Why are my values of authority and hub centrality equal?* I'm getting the same values for authority and hub centrality. ex: v_id hub authority 1, 0.401326450573, 0.401326450573 2, 0.614525497348, 0.614525497348 ... *Code:g.vp.authority = g.new_vertex_property("double")g.vp.hub = g.new_vertex_property("double")eig, g.vp.authority, g.vp.hub = graph_tool.centrality.hits(g, weight = g.ep.edge_weight)* Thais Almeida.
