Hi,

Has anyone encountered this before? I have a few volumes for which mri_watershed output volumes are fine apart from some non-zero voxels near the edges (which are not connected to the brain). The volumes are in transverse format and the most noticeable effect is some inferior slices (neck, lower jaw) which are not being masked out, though there are also some voxels close to the coronal edges. For both sets of edges there is a one or two voxel thick layer parallel to either the coronal or transverse plane.

This is with Freesurfer 4.0.2, T1 images in Analyze format.

Thanks for your time,
Ian Malone
