The BIDS Curation Gear is developed by Flywheel and provided as part of the Gear Exchange. The purpose of the gear is to generate metadata in Flywheel that maps data into BIDS format.
Once installed, the Gear can be run on data within Flywheel (at the session level) by clicking Run Gear, selecting Utility Gear, and selecting BIDS Curation. No additional configuration is necessary, the gear will run against the entire project (or one specific session) and will automatically determine whether to run in initial or update mode on a per file basis. You can learn more about how the templating engine processes files in this article.
Once the gear has run, the BIDS view should be available, and the project and any associated files will have BIDS metadata object in their info.
The curation gear can be run as many times as is necessary. After initialization, the only fields that will be changed by the gear on re-execution are fields with auto_update rules specified, as well as the special properties (valid and error_message)
Please see the README for the BIDS Curation gear for a complete description of providing a template as input and of the configuration options.
