Hi Bruce and Josh,
the sum of all the hippo-subfields included all (the fimbria as well)
except the fissure. We don't have hippo-subfields values related to the
alveus (we run the standard command -hippo-subfields -all).
As suggested by Eugenio and Koen, we are going to use the -hippo-subfields
sure. Good luck
Bruce

I have noticed that Freesurfer tends to include white matter in superior
hippocampus (e.g. alveus), perhaps this is not included in the
hipposubfields volumes?
Wondering, if I were to take a hand traced hippocampus rename it to
aseg.mgz, and made sure that the label matched what Freesurfer
alveus (and fimbria) are defined to be part of the hippocampus in the
aseg. Did you include them in your calculation of subfield hippocampal
volume?

Dear Gari,
The subfield module uses a different, independent method to segment the
hippocampus, and consistency with ASEG results is not explicitly
enforced. That said, the subfield module is inialialized with the ASEG,
and the results should be pretty close to each other, for the most part.
