GUI
To run the WEKA GUI from Hoffman2
- Make sure that you enabled X11 forwarding by including the -Y flag in your SSH command:
$ ssh -Y joebruin@hoffman2.idre.ucla.edu
- Request an interactive node to run on with the following command:
$ qrsh -l i
- Wait for the new node to appear. Your prompt will change from:
[joebruin@login4 ~] $
to something like
[joebruin@n1234 ~] $
- Run the command:
$ java -jar /u/home/FMRI/apps/weka/current/weka.jar
And the current version of WEKA should start up and the GUI will appear.
