External Email - Use Caution Hello Experts,
I ran the PETsurfer pipeline using AV45 pet and performed pvc using pons as reference point. When i looked at the gtm.stats.dat file for one of my subjects, the SUVr for right and left nucleus-accumbens areas were in the negative (left = -0.361; right = -0.046). This is strange because SUVR shouldn't be negative. How do i go about fixing this error? Below, is my pvc command. mri_gtmpvc --i pet.nii --reg register.lta --psf 6 --seg gtmseg.mgz --default--seg-merge --auto-mask PSF .01 --mgx .01 --o subject_gtmpvc --rescale 174 Thanks. Best, Paul
