Follow the same procedures that you used to get the input (--y) to mri_glmfit, then run
mri_segstats --seg cache.th13.abs.sig.cluster.mgh --i y.new.mgh --excludeid 0 --avgwf avg.thickness.dat
The avg.thickness.dat will be a file with a row for each subject and a column for each cluster

Hi Freesurfer Mailing List,
I have just completed a GLM analysis with monte carlo correction and now have my "cache.th13.abs.sig.cluster.mgh" files showing the significant clusters for a specific contrast. I would now like to get mean cortical thickness values for these ROIs in another unrelated MRI sample. What is the simplest means of mapping these clusters to my other sample so that I can extract the stats?
Kind regards,
