I think these are not grey matter but cortical parcellation. 
FSL can output grey matter segmentation but I do not think freesurfer has such an output.
In aparc.stats (rh.aparc or lh.aparc), there is only GrayVol and no intensity measure. I want to know how I can measure the intensities for the grey matter regions.

Recon-all outputs these 3 aparc aseg volumes:

 

aparc.DKTatlas+aseg.mgz

aparc.a2009s+aseg.mgz

aparc+aseg.mgz

 

 

Are these what you are looking for? They should work the same way as aseg volume.

 

Best,

Hi Freesurfer team, 

 

Recon-all output  shows the white matter volumes and white matter  intensities of different brain regions but only shows grey matter volumes. I want to know if there is a function or a flag to also get information on the regional grey matter intensities.

 

Thank you.
