Hello Mam, I am not replying to your mail, instead I need to know the source where you learn Freesurfer and pre processing of MRI and PET. Please do reply.

External Email - Use CautionDear experts,
I am trying to do PVC on FBB-PET images using the following commands:
" mri_coreg --s s_001 --mov s_001_pet_fbb.nii.gz --reg s_001_pet_fbb.reg.lta
mri_gtmpvc --i s_001_pet_fbb.nii.gz --reg s_001_pet_fbb.reg.lta --psf 6 --seg gtmseg.mgz --rescale 174 --default-seg-merge --auto-mask --mgx .1 --o s_001_pet_fbb "
The problem is that when overlaying the mgx.ctxgm.nii.gz file with the T1.mgz of the corresponding subject, they don't match, since the resulting MG-image is in the space of the original PET (without PVC) instead of in the space of the freesurfer subject.
How can I make the MG image be in the freesurfer's subject space? Where is the error? Thank you very much in advance.
