Move and rename IntendedFor field from fieldmap to functional image #39

Open tsalo opened 3 years ago

Under the current BIDS Specification, the field defining which fieldmaps are associated with each epi image are defined in the fieldmap. Accessing this information requires some kind of backwards logic and searching through all fieldmap metadata to find which ones correspond to a given file, my solution to this is moving the field to the epi image metadata in a new field like AssociatedFieldmaps or AssociatedDistortionmaps, meaning the information as to which fieldmap is associated with each image is easily accessible by calling that epi images metadata.

I would like to agree in particular with using the field name

AssociatedDistortionMap

Given that https://github.com/bids-standard/bids-specification/pull/622 was merged into the specification, I think this proposal could be amended to "Remove IntendedFor field in favor of B0FieldIdentifier and B0FieldSource".
