there are separate labels in the aseg.mgz for things like lateral and third ventricles. You should be able to find it in there, or in the aseg.stats file for summary measures like ventricular volume.

Thanks a lot. Actually, I also didn't find the separated csf after segmentation. I am not sure whether I am on the right way. I just want to ensure.

not sulcal CSF (which you really can't get from just a T1), but you can measure ventricular CSF On Wed, 17 Mar 2010, Xiaoying Tang wrote:

Hi All,

Is it possible to get only csf via using freesurfer to do segmentation?
