Hello Everyone,

I have an application outside freesurfer where I need the scalp/face surface from the MRI file so I'm trying to use mri_watershed algorithm to generate the scalp surface, but when I read the subject-outer_skin.surf file in matlab using the read_surf command I see that the facial features (nose, eyes, lips, chin) are not clear. But when I viewed the MRI file using mrilab I can see the facial features clearly. So I was wondering if there are parameters I can change while running the mri_watershed alrgorithm so that I can get good face shape. I'm also up for any suggestions/hints.

Here is the command I used to run the mri_watershed: mri_watershed -atlas -useSRAS -surf /../../bem/watershed/subject /../..subject/T1.mgz /../../bem/watershed/ws/

Thanks and Regards,
