External Email - Use Caution        

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, 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. 

Best regards,
