The BIDS community is preparing to merge the Common Derivatives extension. The updated draft is available for review at [
bids-specification.readthedocs.io], and comments and suggestions may be submitted on GitHub at [
github.com].
The scope of this extension is establishing a set of common principles for organizing derivative datasets, dataset-level metadata, and naming conventions for minimally preprocessed files. Additionally, some common imaging derivatives (e.g., brain masks) have been specified. More detailed modality-specific derivatives are scheduled for inclusion in the next few months.
The final review process entails a minimum of one week for public comment, with a possibility of extension for unresolved discussion. Once public comments are concluded, there will be a one week freeze, during which only critical issues will be considered. (For more details on the release protocol, see [
github.com].)
We look forward to hearing your feedback!
