Hi John
if you run recon-all -qcache for each of your subjects it will generate a set of smoothed thickness maps at a set of predefined smoothing levels on the fsaverage surface. You can then use e.g. mri_average to average them. I'm pretty sure Doug has tools that can do this in one step...
cheers Bruce

Dear Freesurfer community, I want to visualize the mean cortical thickness map of 20 subjects. I ran the command recon-all on the the T1 images. How can I visualize the mean cortical thickness of one group.
Thanks for any advice John
