You can run mris_preproc on each group separately. Then run mri_glmfit with the --osgm flag. The rstd will be the group std, and the osgm/gamma.mgh will be the group mean. You can also call mri_concat on the group files with --mean and again with --std doug

Dear list,
I would like to calculate mean and stdev of thickness group-wise. Could you please give me a hint how to do it?
