Re: [Freesurfer] scalp surfaces - mri_watershed vs betsurf

Hi Darren,

I can't really make much out from this image. What specifically are you concerned about?

Dear Bruce, Steve, et al,

have you compared the output of mri_watershed with betsurf?

I ran a T1 volume through mri_watershed with the -surf output options. I also ran the same volume through betsurf. When comparing the two volumes, I specified an offset of -128 for the betsurf output. I expected a close correspondence between these surfaces. There is a slight rotation difference (see image attached).

Have you seen this before? Steve, is there some reason the betsurf output could be rotated?

Thanks, Darren
