[Freesurfer] PETsurfer issue

External Email - Use Caution

Hello,

Wondering if anyone has had issues with PETsurfer partial volume correction. When I have used it, there are large 'holes' in the white matter. I am mostly interested in the hippocampal area, which seems unaffected by these holes, but I'm not sure if I should trust the outcome enough to still use PVC maps for the hippocampus! Any help is appreciated. Thank you!

I am running this: mri_gtmpvc --i SUV-30-60-float-FixedSlope.nii.gz --reg SUVtoFS.reg.lta --psf 5 --seg gtmseg.mgz --default-seg-merge --auto-mask PSF .01 --mgx .01 --o gtmpvc.output.nopons --no-rescale
