Dear Antti, There’s no specific longitudinal version of the thalamic nuclei yet (hopefully one day…) You could naively segment the subjects in a cross-sectional fashion, but I’d highly recommend that you run the main longitudinal stream first (https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalProcessing) and then run the thalamic module on the longitudinally processed subjects. Cheers, /Eugenio

External Email - Use Caution Dear FS experts,
I'm using the thalamic nuclei segmentation on T1-images. Is it possible to perform longitudinal analysis with this data, or could I just segment the different time points separately to see volume reduction of specific nuclei?
Best, Antti Cajanus PhD student
