***** To join INSNA, visit http://www.insna.org ***** Hi, I have run into a small problem, where I want to intersect two network graphs which are longitudonal snapshots of a network in time. Since sometimes accounts go missing I will have to do an intersection of the networks and find the actors which are contained in both. Is there a good way of doing this? N1: A, B, C, D, E N2: A, , C, D Result: A, C, D I could go through the network files and check if the node-names can be found in the next snapshot, but I think some of the tools out there probably has a solution built in. Did anybody run into this problem before?
