I am preprocessing a dataset where participants had a blood draw completed between scan 1 and scan 2. Participants stayed in the scanner during this time, however, for some participants this resulted in a motion between scans. When the scans are concatenated this produces max displacements ranging from 5-13mm.

Any recommendations on how to handle this data? Should these scans not be concatenated during preprocessing?

Thanks
