Merge update | "rec" & "mod" descriptions #65

Closed KirstieJane closed 4 years ago

KirstieJane commented 5 years ago

I'm currently merging changes to the bids specification into our repository to keep us in sync with those changes.

The point of this issue is to note where there are conceptual merge conflicts (rather than just git not knowing which line information should be on!) so we can review and discuss them.

Specifically, we need to review the section The rec entity in src/04-modality-specific-files/01-magnetic-resonance-imaging-data.md which I've created in the sync-bids branch as a combo of the current bids specification and our proposed updates.

I think this section should be moved out of the rec- section to a new heading for mod- entity. What do you think?

If the structural images included in the dataset were defaced (to protect identity of participants) one CAN provide the binary mask that was used to remove facial features in the form of _defacemask files. In such cases the OPTIONAL mod-<label> key/value pair corresponds to the modality (as stored in the suffix) of the acquisition eg: T1w, inplaneT1, referenced by a defacemask image. E.g., sub-01_mod-T1w_defacemask.nii.gz where T1w is the scan suffix which becomes the value for the mod- entity.
