Hi Matthew, I'm not sure what the issue could be. If you start octave from the command line and type "which fast_contrastmtx" does it say it is not found?

Dear Surfers,

 

I was running mkcontrast-sess with Matlab and having good success.  Then wanted to try Octave for ease of use on a cluster I have access to, and after browsing the listserv set the following:

 

export FS_USE_OCTAVE=1

export FS_OCTAVE_LIB=/usr/lib64/octave

export FS_OCTAVE_BIN=/usr/bin/octave

 

However when I run mkcontrast-sess now (on the cluster and a VB ubuntu machine, both without Matlab), it runs through launching Octave and then errors out as noted below.  I’m new to using Octave and wasn’t sure what else I might need to set up for it to run properly?  Any thoughts would be much appreciated.

 

Best Regards,

 

Matthew
