Hi FSL experts,
I want to know if it would be wise to perform a BBR on PET data (6 volumes, 2mm isotropic) using the command epi_reg. I have an MR image (an MPRAGE) that I would use for the segmentation, done on the same subject but obviously done on another day and a separate scanner so the spaces would be different. Would it be better to just do a regular registration on the PET data? My goal is to have everything in anatomical space so I can make comparisons with an EPI.
