Can't get results about networkanalysis HOT 4 CLOSED

This is more than a year later, but I am getting a similar error.

Reading edge list from '/home/subhajit.sahu/Data/web-Stanford.mtx.tsv'.
Error while creating network: For each node, corresponding elements of neighbors array must not include duplicate values.

I am using graphs in Matrix Market format from the SuiteSparse Matrix collection, and converting to a TSV file with a script. Is this because some vertex u have duplicate edges v (do such duplicate edges exist in the dataset), or is it due to self-loops?

I get this error: "Error while creating network: Elements of neighbors array must have non-negative values."

Could you please help out? Thank you!

The message is reasonably self-explanatory I think? It means that for some reason your input file contained a negative value. I'm not sure what's wrong with the input file, but you'd probably want to double check.

P.S. Apologies for the late reply!

Thanks for bumping the issue @wolfram77 !

Well, it's actually a quite distinct error. Indeed, for some reason your input file contains duplicate values. It's not about self-loops. Do note that the input is expecting only one pair of nodes (unless you provide a pre-sorted edge list, see --sorted-edge-list), so if it already contains the link 0 1 you shouldn't also have 1 0 in there.

Oh, the web-Stanford is a directed graph. I will convert it to an undirected one and try again. Thanks.
