Hi Michael,
if cerebellar gray matter is not something you are terribly interested in
quantifying then you are fine.
cheers

Hi all,
We've using version 5.1 to conduct a longitudinal study involving over 150
subjects with up to three time points apiece, and we're having
some issues with regards to aseg in the areas around the cerebellum. Attached
is an image of the problem - some dura or something else is
being classified as cerebellum. It's particularly troubling because this issue
is present in most of our images, but to varying degrees.
We've tried adjusting the watershed parameters (using multistrip) as well as
using gcut, but neither method was effective in removing the
offending voxels.
It seems like our only other option is to manually edit the brainmask.mgz, but
with so many subjects and time points, we're wondering if
there is another automated fix that we haven't tried. Otherwise, is this
something that we'll have to manually fix, or can it be left
alone?
Thank you,
Michael Murray
