External Email - Use Caution        

Hello,

I had a question regarding the aseg.stats and was hoping to get some help.


1.       How is the TotalGray calculated? On the wiki page it mentioned that it 
is the sum of lhCortex + rhCortex + SubCortGray + CerebellumGM. I tried 
calculating this based on the formula but got different results.

a.       TotalGray (from the aseg.stats) = 751765.612392

b.      298534.487540 (lhCortex) + 287682.124852 (rhCortex) +  58860.000000 
(SubCortGray) + 49.3682 (L_cerebellum-cortex) + 50.1232 (R_cerebellum-cortex) = 
645176.103792



2.       We have subjects that were processed in v4.0.4 and v6.0.0. Since the 
TotalGray measure did not exist in the v.4.0.4, what could we use to calculate 
the volume?

Thank you so much in advance for your help!

Best,
Da-Yea
