Implement two-level modelbuild for longitudinal registration (--two_level) #352

Open Gab-D-G opened 10 months ago

Gab-D-G commented 10 months ago

As requested in #350 , it would be useful to have a two-level registration framework for proper longitudinal alignment (i.e. register first within subjects, and then across subjects). This would require pairing all runs/sessions for a given subject ID, running modelbuild within subject, i.e. GenerateTemplate interface, then taking the subject averages for a second iteration of modelbuild now across subjects.

This will require create a new commonspace registration workflow conducting these operations, and also adapting the associated resampling operations to incorporate an additional set of transforms for the within subject step.

Upon revision, handling the session information will require substantial revision of the current workflow iterables. At the moment, the subject and session information are collapsed into a single split, and are not distinguished at any point in the pipeline. To introduce a separation between subject and session, the initial BIDS reader will need to be modified, and then a new iterable node will need to be introduced to separate sessions. Additional JoinNodes will be necessary as well to accomodate the changes.
