Hi Bruce, Thanks for responding. We do have T2, but not PD. Of course the resolution of the T2 is much lower (5mm slices). -roddy

Hi all,   Trying to get mri_watershed to give me a good inner_skull_surface, which I want to combine with the pial surface to estimate sulcal CSF, as I don't see any other way. Unfortunately the data I have tested on all generate unreliable inner_skull surfaces. Can anyone provide a tip for optimizing the result?   Thanks   -roddy
