What command did you use to apply the transform? If mri_convert add -rt nearest to your command line. The issue is that you are using trilinear interpolation our a label map instead of nearest neighbor

External Email - Use CautionDear FreeSurfer experts
I did brainstem segmentation using BrainstemSubstructure method. Then after segmentation, I aligned all my segmented brainstem to Talairach coordinates using transform=$SUBJECTS_DIR/$s/mri/transforms/talairach.xfm. Alignment seems to be fine. But the boundary of the aligned brainstem looks distorted with different other colors. Why does the boundary look like this? and how can I improve this? I have attached the image of brainstem after alignment.
Thanks in advance.
