Does mri_mask work?

Thank you, Douglas!
Is there a way to mask my functional ROI with these binarized aparc ROIs?
I guess what I want to do is: ROIfunctional * ROI_precentral_binarized > masked ROIfunctional limted to precentral region
best regards, Bastian.

Try using mri_binarize on the aparc+aseg.mgz volume (aparc+aseg has the same ROIs as aparc but in volume format). You can map this into your functional space. doug

Dear Freesurfers,
Is there a way to mask a custom ROI (or label) with a volume / label from automated parcellations?
I have an overlay with fMRI activations and am only interested in the precentral cortex (as segmented in rh.aparc).
I could do masking either on the label level (fMRI activation label * rh.precentral.label) OR on a volume level (fMRI ROI volume * rh.precentral volume)
ultimately, I would only be interested in surface thickness of my fMRI hotspots limited to the precentral cortex.
So the most elegant way would be if there were a function in mri_segstats that allows outputs of thickness values to be "sorted" by the automated parcellation.
But any help leading there is appreciated!
