Good question! It’s ok if only the hippo is covered.

(incl Amygdala) FreeSurfer_dev version
External Email - Use Caution
Dear Juan,
Thank you very much for you answer! However, I ran into another issue using the
new tool: It is stated: 'Using the additional scan in isolation is advised
when it is of higher resolution than the T1 while covering the whole hippocampi
and amygdalae'. Can I still use this processing mode, when my high-resolution
scans only have the hippocampi covered, as I am not interested in the amygdala
in the first place? Or is it mandatory to have both structures fully covered
within the additional scan when I want to run it in isolation?
Thank you very much,
René

Hi Rene,
The atlases are slightly different so the outputs will be a bit different. But
the segmentations will indeed be comparable.

Subject: [Freesurfer] Hippocampal subfields FS6 vs. new hippocampus tool (incl
Amygdala) FreeSurfer_dev version
External Email - Use Caution
Dear all,
I recently saw that the page of the hippocampal module for FS6
(https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields) seems to be
obsolete and it looks as if this module will be replaced by a newer version in
the near future (now dev version,
https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAmygdala).
However, I am not entirely sure how those two modules differ in terms of
hippocampal subfield segmentation, when the "FS60" parcellation scheme is used
in the new module. It is stated that 'it mimics the FreeSurfer 6.0 hippocampal
module', but is the output 1:1 comparable?
Thank you very much and kind regards,
René
