Hi Will,

I think lh.ribbon.mgz and lh.ribbon.mgz contain the volumes of the left and right cortical gray matter.

You can extract a list of vectors on a 1 mm grid which fills these regions using mri_cor2label and count the vectors.

Regards,

Don

Subject: [Freesurfer] Cortical gray matter surface area

Hi all,

I messed up this question recently so just want to clarify and try again. We want to know the cortical gray matter surface area of our subjects but are unclear about how to get this info.

?.aparc.stats reports:

Measure Cortex, WhiteSurfArea, White Surface Total Area, XXXX, mm^2

How about the gray matter?

Thanks,

Will
