Dear experts,

I have a encountered an Error while doing skull-stripping using freesurfer on my T1 weighted images, using mri_watershed

I am using the following command:

mri_watershed -atlas mprage_RPI.mgz mprage_skullstrip.mgz

and here is the error:

mri_watershed Error:
w=White Matter =Intensity too high (>240)...valid input ?

I checked the images, actualy White matter intensity is around 300 .

How could I overcome this issue?

Bests,

S.
