Dear Doug,
Thanks for your earlier reply. I have installed fsl on my machine, and have
progressed a little further through the retinotopy analysis. However, I now
have the following error.
ERROR: TR mismatch between analysis and data
analysis TR = 2, data TR = 0
I used
mri_convert f.nii f.nii -tr 2000
to try to fix the problem, but had no success (below is the output).
Your help would be very much appreciated.
Thanks in advance
Kiley

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
K

Subject: mkbrainmask-sess
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
