Hi Mohamad
the wm.seg.mgz is the output of mri_segment and is a voxel segmentation
that considers local intensities and estimated cortical geometry, but not
topology. mri_pretess then takes the wm.seg.mgz and removes certain
pathological voxel configurations (like corners touching) that mess up the
subsequent tessellation and creates the wm.mgz
cheers

Dear Fs Experts,
What is the difference between (wm.mgz and wm.seg.mgz)_ in the output of
recon-all? i.e is wm.mgz means the whole white matter (right_left
hemispheres and brain stem except the cerebellum)
Thanks
Mohamad
