Hi Jeremiah, How do I eliminate cases like this? (not connected vertex) For you post I think you cannot use "isnan" or "isinfinate" right? My only option is colormap or predecessors? (I havent use them yet) Best, Tasos

Yes, or pass the actual floating-point infinity as the infinity in dijkstra_shortest_paths; if you do that, you should be able to use isinf(). -- Jeremiah Willcock
