Dear Antonio, For the Bayesian network, the entry point is segmentThalamicNuclei_DTI.sh. So, after sourcing FreeSurfer, simply run segmentThalamicNuclei_DTI.sh as explained in the wiki (https://surfer.nmr.mgh.harvard.edu/fswiki/ThalamicNucleiDTI). For the CNN, I’ll defer to Jackson (CCed). Cheers, /Eugenio

External Email - Use Caution Messers Freesurfer developers,
I am using the joint segmentation of thalamic nuclei from T1 scan and DTI, but unfortunately I did not achieve results. I installed: Freesurfer 7.4.1, OS Ubuntu 22.04.5 jammy and VM Oracle 7.0.6 r155176.

CNN segmentation does work, previous steps were performed accurately and without errors.

Answer:
Illegal instruction (core dumped)
How can I do to solve these issues?
Thank you in advance,
