Karl,

fsaverage should be included in the $FREESURFER_HOME/subjects directory of the distribution. Its used as the common-space subject upon which to sample the group data. See the group analysis tutorials on the wiki for more info.

Hello,

I have finished the recon-all on all the participants and ready for the group analysis. But I didn't find the fsaverage. Did I miss someting in the recon-all? How can I get the fsaverage (If I have two groups, do I need fsaverage for each group)?

thanks a lot!

Karl
