Yes, though that will normalize by the pons. If you want to normalize by
something else, you will need to specify it with --rescale. Eg, if you
want to normalize by ceberbellar gray matter, add
--rescale 8 47
Where did you get "6" from for the psf?

Hi Douglas,
Thanks for your reply. We used different tracers for diagnosis of AD
or other neurodegenerative diseases, including PIB, FDG, Flutemetamol
and TAU. If an SUV analysis is used, is it done by mri_gtmpvc? Is
there any subsequent analysis needed?
This is my mri_gtmpvc command:
mri_gtmpvc \
--i
$SUBJECTS_DIR/sub-QM001/pet/sub-QM001_ses-001_trc-C11PIB_rec-05MINS_run-001_pet.nii.gz
\
--reg
$SUBJECTS_DIR/sub-QM001/pet/sub-QM001_ses-001_trc-C11PIB_rec-05MINS_run-001_pet.reg.lta
\
--psf 6 \
--seg $SUBJECTS_DIR/sub-QM001/mri/gtmseg.mgz \
--default-seg-merge \
--auto-mask 1 .01 \
--mgx .01 \
--o $SUBJECTS_DIR/sub-QM001/pet/gtmpvc.output
Is this command okay?
Thanks,
Angel

you cannot apply kinetic modeling to one frame. What is you ligand?
For a one frame acquisition, you usually use an SUV analysis.

Hi experts,
As stated in the subject, can kinetic modeling be applied to PET data
with only one frame? Or we just stop at ROI analysis without kinetic
modeling?
Best,
Angel
