Hello,

I’ve been using PETSurfer for partial volume correction of PET images using the 
RBV option. I’m amending the parcellations/segmentations to add in 
extracortical areas of high PET signal (to prevent spill-in into the brain), 
and after adjusting the *ctab file this runs successfully.

However, I noticed the output resolution of the rbv.nii.gz image is the same as 
the input segmentation mask, not the expected 0.5mm iso. I’ve run a test 
incorporating the --rbv-res 0.5mm flag into the command line. The output 
rbv.nii.gz image is similar to the previous one (without the –rbv-res flag), 
again not as smooth as the typical output image.

Is it satisfactory to run the command with my amended seg image and the 
--rbv-res 0.5mm flag, and are there any additional recommendations for running 
PVC with an amended seg image?

Thanks very much,

Dan
