However, I've received the same error from corrupted .gephi files, so it could be a problem with a particular data point. Have you checked to make sure everything is formatted right and tried to load different pieces of the graph?

I have also this error message and when I open Gephi, I can't access the Data laboratory and load any excel spread sheets or anything. I really need help on this since I need to work on a project where I need to conduct a network analysis for a presentation. I run Mac OS X 10.10.1 (14B25), it was working fine until a day ago and I tried to fix it by updating to Java 8, then I thought it might be conflicting with this, so I removed Java 8 and reinstalled Java 7 Update 71.
I am able to load a .gephi file that I already created and I can look at the "Overview" of the network but when selecting "Data Laboratory", nothing shows up at all. I actually need to import network files in .csv to create another network and since I can't access it, I obviously can't do it. Any help is dearly appreciated.
I get this following error code message:
java.lang.NullPointerException

Any help how to resolve this and make Gephi work again would be much appreciated.

Gephi 0.8, Mac
Attached is the very simple GEXF file I have, created from Gawk and an Excel Spreadsheet.
Can anyone shed some light on this? All I get once I hit open is the java.lang.NullPointerException dialog box and then nothing at all.

Anyhow, thanks a LOT !
btw, is there a tool or a schema that can validate a gexf file?

The importer could check this and display a more useful message, but it is difficult to have every case in mind

me again
I've been doing a lot of Gephi programming and thinkering and I've encountered a problem. I have a network file, dynamic one, containing ~200 nodes and ~13k edges. When I try to load it in Gephi (0.7beta) I get a popup window with the message "java.lang.NullPointerException". I've tried minimizing the amount of edges and the file loads when the network has ~650 edges... which is really really strange, cause I've seen people on this forum loading ~100k edges!!!
I would really be glad if you could help
Attached you will find the network gexf file!
Thanks!!!
