Hi Daniel - What is the age range you're interested in? We have used tracula with children as young as 5 (see example ref below). Keep in mind that tracula is not a traditional template-based approach that needs perfect alignment to a template, because it finds tracts based on their relative position with respect to the labels in the individual aparc+aseg, rather than their absolute coordinates in some template space.

For neonates, we have a new training set of manually labeled tracts in neonates that can be used by tracula. That option, however is not yet in the official freesurfer release.

Hello,
Is it possible to run TRACULA on baby/children brain scans? If so how would one go about doing this?
Could I just change
set mnitemp = $FSLDIR/data/standard/MNI152_T1_1mm_brain.nii.gz
to a different baby/child atlas? If not how would I go about this?
