looks like it is only different in the first or second decimal place, is
that right? If so, then it is acceptable.

in the similar format as gtm.stats.dat file from non-pvc corrected PET data, in

Hi Douglas,
All the analyses have been run with FS version 6 indeed.
If you confirm the commands below are correct, I therefore assume I should
rerun all the analyses using FS 7.1.
I just have few remaining questions:
1. Are there any other ROIs mo

Yep, unfortunately MG values are always much higher than SGTM ones (in

what ligand are you using? Do you expect it to be higher in GM and in WM? What
are the values in the gtm.stats file relative to when you run it without PVC?
How did you choose 5 as the --psf?

Dear FreeSurfer experts,
Originally, I want to use RBV method for pvcorrected PET for SUVR analysis.
After generating gtmseg and coregistration to make lta file, I followed
this code and changed some.
*mri_gtmpvc --i PET.nii --reg subj1.reg.lta --psf
