What is TLRC? Otherwise, it sounds reasonable. I'd definitely look at the image to make sure:)

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
