Resolved Missing Graph Window
Posted: 27 Jan 2014 00:48
Platform:
Mac and PC Gephi version 0.8.2 beta.
Recommend Action:
Increase memory allocation for number of nodes (as recommended on gephi.org)
https://gephi.org/users/install/#memory
There was another URL that showed a performance table which I have misplaced at the moment that indicated memory to number of nodes.
Problem:
All imported sample data ~<4k nodes were working. My data that I started building ran up around the same number of nodes.
What would happen when I loaded the project file, I would see the graph blink for a second and go away. I was having blank screen afterwards. I believe this went for the graph window and not the preview window, but of course the analysis work is done in graph window.
Resolution:
When throwing data into Gephi, I was freely throwing the label into the Id column for nodes. My Edges for the data that I was also importing already had the source and target fields with text strings and not numbers.
I exported my data, put it into MS-Access and mapped an auto-number generated Id field that was integer. Once I reimported the data into Gephi that this worked!!!!
Just to clarify on the working data set, node CSV file imported had integers for Id field and for the edge CSV file the source/target fields were also integers, which corresponded with node Id's. My particular problem was that I had long text strings.
