Thanks Doug,
Is there a function in freesurfer that allows to cut a ROI by the
coordinates?

Sorry I mean the talairach transform matrix in
/mri/transform/talairach.xfm.
In this way, no matter how the brain is aligned when the data is
collected, by translating it to a talairach coordinate system,
the brain will be aligned to ac-pc at y-axis, the longitudinal
fissure is aligned to z-axis, so x-axis is fixed. Then x=0 is the
center of left and right hemisphere.
I checked the results it seems ok, but just want to make sure the
logic is correct.
Many thanks!

I have a work-around solution but want to hear your comment
on it.
I use the TLRC transform matrix in mri/transform to
translate the coordinates in native to TLRC, so that the
origin set to anterior commisure. Then I cut the brain stem to
left and right, by x>0 and x<0, then I use the inverse
matrix to translate the left and right brain stem back.
How do you feel about this?
Many thanks!

Hi Freesurfer group,
For some reason, I have to use the left and right
brain stem separately.
I wonder if there is one way to have a midline, to
cut the brain stem into Left and Right?
Many thanks,
Mengxing
