[Freesurfer] segmentHA_T1, mri_segstats: How can I get the PVC uptake for amygdalar nuclei?

External Email - Use Caution

Hello Freesurfer Devs!

I am attempting to extract the tau uptake in the amygdalar segmentations. I ran this command: mri_segstats --seg rh.hippoAmygLabels-T1.v21.FS60.FSvoxelSpace.mgz --i anat_resliced.mgz --sum rHA_stats.dat to try and calculate the tau uptake.

I was able to get an output, but I am unsure how to proceed from here. I basically want to get the pvc uptake of the amygdalar and hippocampal subfields scaled to the pons. I don't think I can run the mri_gtmpvc command, so if you had any insight on how to calculate the scaled uptake of tau in the subfields, let me know!

Best, Samantha
