Do you just want to do an ROI analysis? Or do you want to do a voxel-based analysis? If ROI-based, then follow the steps on the ROI tutorial (ie, aparcstats2table and mri_glmfit with --table input).

Hi Mohamed

Doug is away this week and can give you a more details answer next week. Certainly you could use mris_anatomical_stats -l <BA label file name> to compute the volume/thickness/area for each subject then do whatever GLM analysis you want outside of FS.

Dear Freesurfer users,

I would like to study the between groups changes of volume/cortical thickness of one region (Perirhinal) belonging to the Brodmann areas. I tried to do that with Qdec tool but unfortunately Qdec does not load the Brodmann areas stat list. I am wondering if I could use the GLM formalism with of course regressing out the ITV. Any suggestion/advice will be very welcome.

Many thanks in advance,

Best regards,

Mohamed
