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

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? On Tue, 26 Feb 2013, Joshua Lee wrote: I have noticed that Freesurfer tends to include white matter in superior hippocampus (e.g. alveus),

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. Have
