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/FreeSurfe... https://secure-web.cisco.com/16ntnqYurxLXfYvZCsM5evs9fxRFquoTnxIkD0H4vCmJ3wyz1ILXajrnEbC8QyD23IXTjhznWNEd6JY41T_1i4pFiAhYAmIiof9tTBS1o1Uv6Xe0jQ8zZK9BhCaaj7eG9eskRi7K2wraMBF5F1EQuFvn37XsurmsDLZ0IDBk02St-7AjIKjoN_btWKXbQQ_GjGriTaQKWn4oNTTT1J4WJiO73HLMdnC4N3JLqbQ0M7Rv8LV2WSnPMBUXHQA8R1nK869ZmYnfSz43n0gGUGW4dwGx6BqLbae0K35hubuWgxRFxCSpAMGc4xDZWv753Hyn8XTc1jpc5Dq57MVQ-eWsDRQ/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FFsTutorial%2FAnatomicalROI%2FFreeSurferColorLUT)

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!
