These are segments in the wmparc.mgz file. Originally, I called these centrum semiovale, but I realized that, while they might overlap heavily with CS, it they were really just voxels left unsegmented by the main process and I did not really know that they were a good segmentation of CS.

Dear Freesurfer team,

I was wondering if FS has a way to segment the centrum semiovale?

The freesurfer colorLUT table mentions "Centrum semiovale is also labled with 5001 (left) and 5002 (right)." (see MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI/FreeSurferColorLUT)

What does the "also" refer to in this description?

Do the following rois represent the centrum semiovale ? :
5001    Left-UnsegmentedWhiteMatter                     20  30  40  0
5002    Right-UnsegmentedWhiteMatter                    20  30  40  0
Thank you for your help!
