I´m using NodeXL to get the data from Twitter. For the analisys and the graph displaying I´m using Cytoscape and Gephi.
How can I use NodeXL to only get the data from the Twitter API?

Thank you very much for the answer.

The easiest way is to download and install the NodeXL Excel Template, if you haven't done so already.  It's available at http://nodexl.codeplex.com/releases.

In the NodeXL Excel Template, go to NodeXL, Data, Import, and select one of the Twitter networks from the Import menu.  This will get a network from Twitter and store it in the workbook.  Then save the workbook as an "Excel 97-2003 Workbook (*.xls)".

According to the Cytoscape help file at http://cytoscape.org/manual/Cytoscape2_8Manual.html#DelimitedText Table and Excel Workbook, Cytoscape will import graph data from an Excel .xls file, so you can import the Twitter network data from your Excel workbook.  I don't have Cytoscape and so I haven't actually tried this.

Exactly. As I said, the problem is that when I try to import an account with more than 150.000 followers NodeXL eats up all my memory and crashes. I just need the vertex data and nothing else. Is it possible to get the data without the whole processing? May be, that way the program continue running.

My apologies.  I didn't notice that you were the original poster; I thought that an unrelated post had been tacked onto the topic.

If you can't solve the out-of-memory issue using one of the suggestions I made in my original reply, the only other thing you can do is limit the number of followers you import.  You can do that in NodeXL's Import from Twitter User's Network dialog box by checking the "Limit to N people" checkbox.
