External Email - Use Caution Correction Lilla,
I think they are nih atlases in the 21-27mo age group.. We are analyzing the 2yo age group. Could we use the baby FS atlases at that age range since they have the CC segmented to generate the CC on our asegs with the method you suggested below?

Will using Tracula even work at all or will it generate the other tracts but not include the CC minor/major tracts?

Note that, for the new TRACULA (in FS 7.2), we recommend also running the thalamic nuclei segmentation, as it helps with the accuracy of the tracts that terminate or neighbor the thalamus.

Is this correct? How would we run trac-all if we only had an aprc+aseg from another pipeline that generates FS-compatible outputs? For example, trac-all -preproc -bedp -path -c (where c = dmrirc config file).
