It could be. It uses fsl only to create a mask of the brain, so it
probably does not need a full fsl install, but it might need more than
you have.

Hi again,
Could this error be due to the fact that I don't have a full version
of fsl installed and configured on my ubuntu virtual machine? i.e.
does fsfast require fsl to be installed?
Thanks

Dear Freesurfers,
I am currently trying to do some retinotopic mapping. I have been
successful in running the reconstruction commands and setting
everything up for the analysis, but I have run into problems when
using the selxavg3-sess command. i.e. selxavg3-sess -a rtopy.self.lh
-s IFEE2211 -no-preproc ( -no-preproc since I have co-registered and
motion corrected my files in SPM).
I was unable to run this command as freesurfer could not find
/media/sf_DATA1/RETINOTOPY/IFEE2211/bold/001/global.meanval.dat
So I ran mktemplate - sess, which was successfully completed. And then
I ran mkbrainmask-sess (see below).
Any help with this would be much appreciated.
Thanks
Kiley
