I'm not sure what you are looking for as it is just the equation of a
gaussian. The PSF is given as the full-width-half-max. This is converted
to a std dev with
gstd = fwhm/sqrt(log(256.0))

Dear experts,
I'm employing PETsurfer for partial volume correction.
Could you share the definition or formula you use to define the psf (flag
--psf of mri_gtmpvc) that is used to correct the PET image?
I understand that it is an isotropic gaussian
