Hi Sara,
You may want to try --meas volume in place of --meas thickness when running mris_preproc.
I would also recommend looking at our ROI Analysishttps://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROIV6.0 tutorial and Volumetric Group Analysishttps://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/VolumetricGroupAnalysis?highlight=%28thickness%29%7C%28volume%29%7C%28measure%29 tutorial. Please let us know if you are still having trouble.
Cheers, Jocelyn ________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of Sara Lyn saralyn543@gmail.com Sent: Monday, December 7, 2020 10:43 AM To: Freesurfer support list freesurfer@nmr.mgh.harvard.edu Subject: [Freesurfer] group analyses

Hi FS developers,
I ran mris_preproc, surf2 surf and glmfit and cluster analyses (monte carlo) for a surface based thickness group analysis. I am trying to extract volume measures from the same significant thickness ROIs. Is there any way to do this? Thank you!
Sara
