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.
