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 Analysis tutorial and Volumetric Group Analysis tutorial. Please let us know if you are still having trouble.

Cheers,

Jocelyn

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!
