41 is the code for Right-Cerebral-White-Matter. We do not explicitly represent that in the aseg.stats. Rather, it is rhCorticalWhiteMatter that is stored in the header portion. If you run asegstats2table with any other segno (eg, 17), it will give you 17 plus a lot of global measures. One of those global measures will be rhCorticalWhiteMatter.

Could anybody help me with the --segno option during a asegstats2table process. I've run my subjects under recon-all and I am pretty sure the data exists under the stats folder but when I ran:
asegstats2table --subjects <MysubjectFolderName> --tablefile aseg.txt --skip --segno 41 (I've tried it with different segnos a s wellŠ)
I got the following error:
SUBJECTS_DIR : <THE_CORRECT_FOLDER_LOCATION> Parsing the .stats files Building the table.. ERROR: cannot find the corresponding segmentation for the id:41 you provided in any of the .stats files parsed
