Dear Freesurfer Team,
This is a follow on to the question regarding manual validation results for the FS 6.0 hippocampal subfield total mask. Could you please also comment on the similarities and differences between the hippocampal subfield summation (ORing of the subfields) and the HARP manual protocol definition, and whether FS 6.0 aseg hippocampus and the subfield summation have been directly compared to the HarP validation set (Boccardi et al, 2015) using a DICE approach on same subjects? These questions pertain to the hippocampal subfield segmentation atlas prior to the more recent inclusion of amygdala, but the same questions regarding manual validation images and masks would apply for the latter as well.
Thanks again,
Dawn Matthews
