yes, you can use --psf-col, --psf-row, and --psf-slice. --psf-col is the FWHM in the left-right direction (when the images are axial), --psf-row for the anterior-posterior, and --psf-slice is in the z-direction

Hello,

Is there a way to specify a nonisotropic PSF when using mri_gtmpvc? I have reason to believe there are differences between the axial and transverse resolutions of the PET scanner in my study and would like to incorporate them if possible.

Thanks,

Ian Kennedy
