Hi Caspar, with 5.1 you would not use any of those programs (ie,
func2sph, isxavg-re-sess, or isxavg-fe-sess). If you want to use FSFAST,
then see the tutorial for getting started. You'll need to set up the
directory structure properly, then run preproc-sess, mkanalysis-sess,
and selxavg3-sess. For the group analysis you'll run isxconcat-sess
followed by mri_glmfit and mri_glmfit-sim. If you don't have anatomicals
for all subjects and you just want to use the average subject, then put
the average subject into the subjectname file when you set up the
directory structure.
