External Email - Use Caution Hello,
I have a question regarding the following PETSurfer command: 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 I have been trying to run the analysis without applying partial volume correction, but it seems like there are two ways to turn it off: One is to set the point-spread function to 0 by adding “—psf 0”, The other one is to get rid of “—psf” altogether and add “—no-tfe”. We tried both and they produced slightly different results. The second method “—no-tfe” produced lower uptake values for each ROI. Which one would you recommend to properly turn PVC off? Thanks in advance! Best regards, Zhener
