Hi Niels,

The atlas is the same, so you’ll get the same regions, but the actual segmentation code has improved since FS6.0 – therefore the 1.1 and 1.2 versions. The results should not be wildly different, though.

Cheers,

Subject: [Freesurfer] brainstem-structures different versions?

External Email - Use Caution

Hi I see on the website of brainstem substructures that the '-brainstem-structures' option in freesurfer 6.0 stable release produces brainstem segmentations that are labeled v10 whereas the script 'segmentBS.sh' available in beta versions of freesurfer produces v11 or v12 segmentations. What is the difference between these versions of the brainstem segmentation? Under what circumstances is the latest version recommended? Thank you for any clarification.
