Does the BIDS format accommodate group-level data?
In my particular case, I have surveys that were completed together by groups of participants. The BIDS spec focuses on the subject level, and doesn’t include (so far as I can see) recommendations for how to handle group level data.
My current thought is to duplicate the data in a group session for each participant, e.g.: “/sub-sid000/ses-group/sub-sid000_ses-group_task-survey_beh.tsv”. But I worry that the data duplication could cause confusion or errors down the road—it would be best if the data could live in a single, unambiguous location.
