If you just use 24, then you will see a small patch near cerebellum. The 257 is not part of the analysis yet. All the others are venticular

THanks for the response, Doug! So just to clarify, when I use mri_binarize with the 24 label, which indicates CSF, I shouldn’t expect to see any CSF in my mask other than that within ventricles? The reason I ask is I’m trying to generate the mask from which to acquire my csf regressor. Would you instead recommend using fslmaths or 3Dseg for that? How do FSL users typically go about it? I suppose I could do a subtraction of GM/WM masks from whole brain masks with a 3dcalc function. Just curious of the most common freesurfer method of acquiring csf regressors. Thanks!

We do not currently segment extra cerebral CSF. We will have this segmentation in the next version.
