- Key Group
A set of scans whose filenames share all BIDS filename key-value pairs, excluding subject and session. The key group is derived from the common BIDS filename elements. For example,
acquisition-*_datatype-*_run-*_task-*_suffix.- Parameter Group
A set of scans with identical metadata parameters in their sidecars. Defined within a Key Group. Numerically identified, meaning that each Key Group will have n Param Groups, where n is the number of unique sets of scanning parameters present in that Key Group (e.g., 1, 2, etc.).
- Dominant Group
The Param Group that contains the most scans in its Key Group.
- Variant Group
Any Param Group that is non-dominant.
- Rename Key Group
Auto-generated, recommended new Key Group name for Variant Groups. Based on the metadata parameters that cause scans in Variant Groups to vary from those in their respective Dominant Groups.
- Acquisition Group
A collection of sessions across participants that contains the exact same set of Key and Param Groups.
