bbregister is more sensitive to the smoothing in the PET images. This can create a confound between atrophy and registration. bbregister should only be used on non-smoothed data.

Hi FreeSurfer Team,
I am currently using PETSurfer to analyze FDG data. Following the guide *MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be* https://surfer.nmr.mgh.harvard.edu/fswiki/PetSurfer https://secure-web.cisco.com/11AP3L-fRQ1NyWLwYgy3qW-ObrGxWQsVDEGWJEidxYaLFleo8x6bV-bdH8eLZwLbRkWinVldOV1qDJy0v2d0UB8jW9t6WaSDIlGCVfwxhg2vbtB12Ci8gqdvbKFx-xKQxdJOqU-cL4kmTWApXkud2Iz_30imjhwVnRqTX2w7sgqflnsIyXNoWDrvLiibLRpvobvmYNOLnKzv9Yxa9tx3CjO4Q0ZhM9oSx7Had2L8N8WCHOMfH9csV5xIk4roG1R2rGvGvBIoXfq6TVWtX0oc3RwbtAzii9QQV0jnAa1c73Js-ALAS8HTzQe_BXdeXzQMmj4wdaASOcKWyJ9Jt5JkKGg/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FPetSurfer, it is suggested that you use /mri_coreg/ to register PET and MRI images. However, I was wondering whether /bbregister/ might not be the more appropriate tool to use, especially in a case like FDG, where we have a lot of uptake in the brain.
