Dear Joana,
at this point, a "true" longitudinal version of the subfield segmentation is not available. However, we have noticed that you can get slightly better (more stable) results by segmenting the subfields in the longitudinally processed timepoints - rather than the original, cross-sectionally analyzed subjects that you used to create the base.
In other words: rather than running
recon-all -subjid tpN -hippo-subfields
you should run
recon-all -subjid tpN.long.base -hippo-subfields
Cheers,
Eugenio

Dear all,
I'm interested in assessing the changes in the volumes of hippocampal subfields between 2 time points.
Can I use the longitudinal pipeline of Freesurfer and add the -hippo-subfields flag to the longitudinal runs of the 2 time points?
Thanks!
