Re: [Freesurfer] Fw: mri_watershed error, White Matter Intensity too high

can you send us the entire output of the command? And perhaps some background? I assume you are trying to use mri_watershed outside of recon-all?

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?
