If you can create an average subject and register your individual surfaces to that subject, then it can be done. By default, recon-all will register to the human atlas to create ?h.sphere.reg

Hi Doug,
thank you very much.
One more question: From the documentation, I wasn't really sure whether it would also be possible to do the analysis of the functional data in a common volume space (not MNI, as it is NHP data).
Thanks again, Caspar

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.
