Hi everyone, When computing the Bonacich centrality of a large, sparsely-connected network (1310 vertices with 6717 edges), i get the following error message:
*Error in .local(a, b, ...) : * * cs_lu(A) failed: near-singular A (or out of memory)* The graph is available via https://www.dropbox.com/s/9ba0l3i9ozm0axe/graph.txt?dl=1 (in graphml format). What i have tried so far: - using both igraphs' "power_centrality" function or the former "bonpow" function provide the same error - computed eigenvector centrality (no errors), alpha centrality (same error), computed Bonacich centrality in UCInet (no errors). - increased memory to max (around 4GB) - checked earlier posts and found one relevant, but unresolved thread about six years ago: http://lists.nongnu.org/archive/html/igraph-help/2009-04/msg00040.html Any help is highly appreciated, thanks in advance! Best regards, martin
