yes, they are, thought I don't know why you include "psf6" in the output folder.

Dear All,

I would like to perform no partial volume correction of PET using PETSURFER. The steps followed in doing this is shown below:

gtmseg --s Patient_1

mri_concat Patient_1_pet.nii.gz --mean --o Patient_1_pet_tac_vol_mean.nii.gz

mri_coreg --s Patient_1 --mov Patient_1_pet_tac_vol_mean.nii.gz --reg Patient_1_pet_registration.lta --threads 4

mri_gtmpvc --i Patient_1_pet.nii.gz --reg Patient_1_pet_registration.lta --no-tfe --psf 0 --seg gtmseg.mgz --o Patient_1_gtmpvc.output.psf6

I would like to know whether these steps suffices for a no partial volume correction.

Thanks.

kate
