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.
Cheers,

* 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/HippocampalSubfieldsAndNucleiOfAmy...).
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
