Dear experts,

mri_gtmpvc --i pet.nii.gz --reg template.reg.lta --psf FWHM --seg gtmseg.mgz

 --default-seg-merge  --auto-mask 1 .01 --mgx .01 --o gtmpvc.output

About this command, is there the possibility for PETsurfer to compute the fwhm of the psf of the scanner without being provided by the user?

If i put psf to 0, there is no PVC, and the same if I don’t put that flag at all.

I wonder if PETsurfer is able to estimates fwhm by itself (doing something like the FWHM of smoothing  in step 8.2).

I hope that my english is enough clear to be understood.

Thank you so much for your kindness,

best regards,

Federica
