Thank you for your kind response I realized my mistake by playing with a python function which replicates the results of avg_neighbour_corr for both "in" and "out" neighbors using an integer vertex property for p1 (the equivalent to "source_deg" in the original function). I posted my own response in the forum, but I don't know if it got to the mailing list... problems with posting before subscription confirmation Just in case, here it goes: scuenda wrote > def avg_nn_corr(g, nn_dir, p1, p2): > kmax = p1.a.max() > dnorm = np.zeros(kmax+1, dtype = float) > dsum = np.zeros(kmax+1, dtype = float) > dsum2 = np.zeros(kmax+1, dtype = float) > if nn_dir == "in": > neighbours = lambda v: v.in_neighbours() > elif nn_dir == "out": > neighbours = lambda v: v.out_neighbours() > for v in g.vertices(): > k1 = p1[v] > k2v = np.array([p2[w] for w in neighbours(v)]) > dnorm[k1] += len(k2v) > s = k2v.sum() > s2 = (k2v**2).sum() > dsum[k1] += s > dsum2[k1] += s2 > pnn = dsum/dnorm > snn = np.sqrt((dsum2/dnorm - pnn**2)/(dnorm)) > return pnn , snn -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/About-avg-neighbour-corr-tp4026410p4026421.html Sent from the Main discussion list for the graph-tool project mailing list archive at Nabble.com. _______________________________________________ graph-tool mailing list [email protected] http://lists.skewed.de/mailman/listinfo/graph-tool
