Dear experts,

Few weeks ago i wrote to this mailing list but I didn't receive any answer, so I'll try again:

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


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

Is able mri_gtmpvc to evaluate the fwhm without receiving it from the user?

I apologize for the repetition,

Thanks for your patience,

Federica
