Hi Rene,

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

Cheers,

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
