Dear Freesurfers,

I have a question regarding thickness analyses using mri_glmfit. I am interested in correlating cognitive performance with a specific region in the brain and to increase the power of my analyses I want to conduct mri_glmfit on only my ROI.  I was just wondering if it is possible to restrict mri_glmfit to certain regions of the brain instead of running them on the entire cortical surface and how I would I go about doing so.

Thanks for your help,

Prapti
