BIDS dataset validation involves checking folder layouts, filename entities, and extensions for structural compliance. It also requires verifying that required metadata sidecars and key files like participants.tsv and events.tsv are present and coherent.

Required BIDS metadata includes the dataset_description.json file for global context, participants.tsv for subject listings, and events.tsv for behavioral task timing. These files must be present and consistent to ensure downstream preprocessing accuracy.

BIDS derivatives should be organized using provenance and naming conventions that align with the source dataset structure. This involves applying modality-aware routing to maintain consistent entity ordering and metadata relationships across processed outputs.

Yes, BIDS specification guidance supports modality-aware routing for EEG, MEG, fMRI, DWI, and behavioral experiments. It helps route analysis questions toward the correct tool family and identifies the right references for each specific neuroimaging modality.

You need a BIDS dataset audit when planning safe data processing to prevent downstream mistakes in quality control. It validates metadata completeness and structural organization, ensuring safety guardrails are met before heavy processing begins.
