The wm-anat-snr script (attached in case you don't have it) is good at picking out cases with motion-related noise. You get one number for each subject, and you can then do a statistical comparison between groups on that one number. doug

Dear FreeSurfer experts,
we did a FreeSurfer-Analysis of cortical thickness in schizophrenia patients with motor abnormalities and found significant changes of cortical thickness in many brain regions. The Qdec p-maps showed many clusters (regions) with "surface" size exceeding 100mm2. We used a 15mm FWHM smoothing.
Does anabody have an idea if there is a reasonable neurobiological/ontological basis/explanation for this finding?
What is the exact size of M1 and SMA in mm2?
Thank you for your time!
