Dear FS experts, 1) First Is it possible to use the partial volume correction provided in the v6 beta version of FreeSurfer despite the fact that recon-all have been done for all subjects with the v5.3 ?
Yes
2) Does this method supply an intensity normalisation for PET images ?
What do you mean by intensity normalization? For uptake analysis, people usually use SUV (standard uptake values where the whole image is scaled by a value related to the injection mass and subject weight) or you choose a reference structure to scale by (often called rSUV for relative). By default mri_gtmpvc uses pons, but you can choose any structure you want with the --rescale flag
Best regards, Matthieu
