Dear Freesurfer List,
I had a (hopefully) quick question re: output files from the hippocampal and amygdala subdivision routines. I know that there are multiple parcel schemes for the hippocampus (HBT, FS60, and CA), and per this thread ( https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg57898.html), the final subfield segments are "computed from none of those volumes, but the parent of all of them".
I wondered however if there was an MGZ file that corresponded to the final/combined sub-divisions? Or if there was a way to output this? My group was interested in doing some spatial and surface analyses of sub-divisions (using Spherical Harmonics or some other related techniques).
And I understand what the different MGZ files were in the mri directory (e.g., CA.FSvoxelSpace.mgz, FS60.FSvoxelSpace.mgz, HBT.FSvoxelSpace.mgz), but what was the file without any suffix (e.g., lh.hippoAmygLabels-T1.long.v21.mgz)? Or is that the file I'm looking for? Any information is deeply appreciated!
Thanks much, Jamie.
Dear Jamie, Sorry for the late response; I was on vacation. If I’m understanding correctly, the file without “surnames” is what you need: [lr]h.hippoAmygLabels-T1.v2x.mgz. Cheers, /Eugenio
