[Freesurfer] Gray matter missed in the pial layer after mri_segment

2013-07-17 Thread Erin Browning
Hello--

We have a set of scans with bad artifact throughout the temporal lobe and
the superior cortex. We've had to do the normalization steps (n3
correction, normalization) manually on most of these scans to preserve the
gm/wm boundary. Now, when we run mri_segment, it leaves out some gray
matter along the pial border. Is there a correction for this? Mri_segment
has wlo and whi and ghi, but no glo, and it doesn't look like there's a
method to add gray matter to the pial boundary like there is to remove it.

Thank you,
Erin Browning
