External Email - Use Caution        

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
