The NodeXL Twitter import sometimes creates the following string in the data "&#" and Gephi won't import that. In 0.8.2 you used to get an error message indicating the errant string so you could delete it with a text editor, in 0.9 there's no error message, Gephi just sits there and appears to do nothing. Maybe see if there's an odd string like that in the data and remove it?

Still wasn't able to resolve the "easy" NodeXL import. What I ended up doing was saving the Twitter data downloaded in NodeXL as an excel file. Then I had to manually manipulate the "edges" and "vectors" sheets in the excel file such that there was a new column in the edges sheet that had the Twitter ID (an integer, not the string username) for both the source and target. I then saved each sheet as a separate CSV and imported individually.

There were only 5k or so of each nodes and edges, so it was only mildly time consuming. This would not be preferable for analysing much larger sets (you can get up to 18k tweets when including friends of those whose tweets are caught in the Twitter keyword search).

As I am unfamiliar with Java, my ability to troubleshoot the errors that popped up is limited. Any insights there?

I updated all of the default gephi plugins, and now I get a nullpointerexception error when attempting to load the file.

Interestingly, if I save the dataset as a csv I'm able to load it properly in geohi, albeit without any edges.

Googling doesn't help me at all. I'm curious because I simply followed the nodexl guide (and all of the nodexl to gephi tutorials are basically the same) to download the twitter dataset and export it as graphml.

Was successfully able to capture Twitter data with NodeXL and export the data to a graphml file. However, when I attempted to open the same graphml file with Gephi, I ran into the following error:

I'm running on OSX v 10.11.6, with Java version 8 update 101

Any thoughts as to how I can resolve this issue?
