Got it, thanks! I have already performed smoothing on the MGX surfaces so I’d like to proceed with mri_surf2vol.
According to the “hidden secrets of success” for mri_surf2vol, there are 2 methods. Is the command below correct? mri_surf2vol --so lh.bp.nii.gz (the PET surface BPNDs) --so rh.bp.nii.gz --subject fsaverage --o smoothed.bpnd.in.volume.nii.gz The next step is to bring the volumes into CVS-MNI152 space. Mri_cvs_register has been done on the T1. Thanks Doug.
