As far as I can tell, intra- and inter-registration do not appear to be linked.
However, it is common for registration to be performed sequentially.
The image sequence closest to a particular atlas sequence is used for an inter-registration step, and then the other sequences are intra-registered with the first sequence already registered.
Therefore, I propose an intra-inter-registration method, to address this issue.
