No special procedures come to mind. You can use mri_segstats using the PVC'ed PET image as input and aux/seg.nii.gz as the segmentation and aux/seg.ctab as the colortable.

External Email - Use CautionDear Freesurfer experts,
As previously mentioned, we are currently trying to test the effects of different PVC corrections on metabolism estimation in a group of patients.
We would like to also include MZ and MG methods in the analyses, comparing them to SGTM and no PVC. However, while both MG and MZ provide voxel-wise results, we would like to use them in ROI analyses in order to be able to compare their outputs with the ones obtained with SGTM and no PVC. Are there any procedures that you would recommend to do this?
Many thanks in advance for any help,
Best,
Pilar

We need the file something like we have for 'aparc' parcellation. The file format should be in .mgz (aparc.HCPMMP1+aseg.mgz) How can i do it? (i have lh.HCPMMP1.annot and rh.HCPMMP1.annot)
