Hi Mohamad, For now, our brainstem module separates this structure into midbrain, pons, medulla and SCP - please see this link: https://surfer.nmr.mgh.harvard.edu/fswiki/BrainstemSubstructures If you want to segment more specific nuclei, we don’t have a tool capable of doing that yet. Cheers, /Eugenio

Hi Iglesias, Kindly, we would like to know if there are any methods in Freesurfer that can help to segment thatbrain stem nucleus. I mean output the nucleus automatically as a small masks, so these small masks can be used in other analyses (e.g. fMRI)
I am thinking of creating masks for these nucleus depending on an atlas. I open the T1 image in Fslview and I create the mask for the nucleus of interest. But this is so hard, not accurate and time consuming. The reason for my question. We highly appreciate any suggestion!
Best, Mohamad
