Dear FS experts: 
How can I get the whole cerebral WM and cortex volume. 

I am using following command: 

asegstats2table --subjects 10001 --segno  2 3 41 42 24 --tablefile 10001_WB_table

It shows that no 2,3, 41,42 segment NO, however, they can be found in the FreeSurferColorLUT.txt file.

thanks
Lawrence
