Brain Imaging Data Structure

Maintained by BIDS community

What it helps you do

Use BIDS when you need dataset layout, filenames, participants, sessions, acquisition metadata, events, coordinate systems, and derivatives across MRI, PET, EEG, MEG, iEEG, microscopy, and related modalities.

01

Where it fits—and where it doesn’t

Use these four checks before committing implementation time.

Use it when
Human- and machine-readable packaging of neuroimaging and behavioral studies for validation, sharing, and reproducible analysis.
Do not use it as
Do not treat BIDS as a complete solution on its own. Passing BIDS validation proves encoded structure, not image quality, biological plausibility, complete metadata, de-identification, or analysis validity. Draft BEPs are not released specification content.
Best for
Teams working with Imaging and Neuroscience data across Acquire → Harmonize → Exchange → Learn + reuse.
Maturity
EstablishedEstablished enough for serious use; still pin the exact release and any implementation profile.

See it in the workflow

A standard creates value by changing a handoff, not by existing in a catalog.

  1. InputWhat starts

    Imaging and Neuroscience data, metadata, and the local decisions around them

  2. BIDSWhat changes

    BIDS applies a shared standard across Acquire → Harmonize → Exchange → Learn + reuse

  3. OutputWhat becomes possible

    A more consistent, reviewable handoff for the next system or team

Readiness gateBefore scaling: Passing BIDS validation proves encoded structure, not image quality, biological plausibility, complete metadata, de-identification, or analysis validity. Draft BEPs are not released specification content.

03

A concrete example

A multi-site MRI study retains source DICOM, converts to a pinned BIDS release, validates every snapshot, and records conversion and derivative provenance separately.

Why it matters: Consistent cohort, acquisition, event, and derivative structure supports scalable imaging ML, but labels, QC, confounding, de-identification, and split governance remain separate.

04

What it fits with

DICOM commonly supplies source clinical images before BIDS conversion; BIDS organizes study-level files while NWB deeply models neurophysiology sessions. DANDI and OpenNeuro operationalize BIDS validation.

05

Implementation starter

Start with one bounded handoff. Pin, test, and review it before scaling.

  1. Name an accountable owner and the decision BIDS must support.

  2. Pin the exact version and companion artifacts: 1.11.1 · 2026-02-19.

  3. Map one representative input to the required standard artifacts.

  4. Test the result against the canonical source and record every exception.

  5. Preserve the source data, mappings, and review evidence before scaling.

06

Limitation to test first—and the tests that catch it

Risk

Passing BIDS validation proves encoded structure, not image quality, biological plausibility, complete metadata, de-identification, or analysis validity. Draft BEPs are not released specification content.

Test

Run one representative end-to-end pilot and record exactly where BIDS loses context, needs an extension, or depends on another standard.

Risk

A structured or machine-readable result can still be unfit for analysis or AI.

Test

Test the output for missing context, provenance, terminology alignment, time leakage, and the intended downstream decision. Consistent cohort, acquisition, event, and derivative structure supports scalable imaging ML, but labels, QC, confounding, de-identification, and split governance remain separate.

07

Why we believe this

Checked against the canonical source plus independent operational evidence from an adopter, regulator, or implementation report.

Evidence notation: E1 + E2. The code is shorthand; the plain-language statement above is the claim.
