Hi,
From https://surfer.nmr.mgh.harvard.edu/fswiki/MorphometryStats
"SubCortGray - includes thalamus, caudate, hippocampus, amygdala, accumbens, ventral DC, substancia nigra (if there). This is a simple voxel count of structures identified as subcortical GM."
Could you please let me know if "thalamus, caudate, hippocampus, amygdala, accumbens, ventral DC, substancia nigra (if there)" is the complete list of structures identified as subcortical GM or are there others?
A simple voxel count of thalamus, caudate, hippocampus, amygdala, accumbens, ventral DC, substancia nigra (if there) does not seem to match the subcortgray value from aseg.stats.
Versions 5.3, 6.0.
Thanks.

That is a complete list
A simple voxel count of thalamus, caudate, hippocampus, amygdala, accumbens, ventral DC, substancia nigra (if there) does not seem to match the subcortgray value from aseg.stats.
The values in aseg.stats are not a simple voxel count -- they include partial volume correction.
Versions 5.3, 6.0.
Thanks.

Sorry, that is not a complete list. I should include putamen and pallidum. This has been fixed on the wiki page
