Gephi forums

Hello,

I want to confirm if Gephi sums up the weights in case of multiple edges between two nodes in a directed network. In a simple example that i created to check this, it did not. The same is the case for an undirected network.

Can any one please confirm this and advise if there is a way I can get the weights to sumed up. The multiple edges in my network are added at different times and thus i would like to retain them.

Thanks

You can save the network in Pajek net format and use Pajek to do it:
Network - Create New Network - Transform - Remove - Multiple Lines - Sum Values

You should be able to do this in Gephi 0.9.2+ by importing a file and choose Sum in edges weight strategy, then import the second file and do the same. Repeated edges weights will be accumulated.
