Validating a BIDS Dataset

The Validate BIDS tool allows you to check your Dataset for conformation with the Brain Imaging Data Structure (BIDS) standard. The tool uses the open-source bids-validator 1.8.4 Python Package.

Before running the Validate BIDS tool, ensure that the Dataset Type is set to BIDS (defined in the Dataset creation step or modified in the Metadata Schemas page under Essential Schemas).

Open

1. Open the Dataset from the Datasets landing page and select the Explorer tab. 

2. Click Validate BIDS. If the Validate BIDS button isn’t visible, make sure your Dataset Type is set to BIDS (see above).

3. The validation process starts. It may take some time to run, especially for large files.

4. When the validation is complete, the results are indicated by icons adjacent to the Validate BIDS tool:

   • Green - Validated, no warnings: A valid BIDS Dataset, no further modifications needed.

   • Green - Validated + orange warning icon: A valid BIDS Dataset with optional recommendations to make the Dataset more BIDS compliant. Click the warning icon to view the explanations. If desired, make the recommended corrections to the Dataset and re-run the validation.

   • Red - Not Validated: an invalid BIDS Dataset. Click the warning icon to view the errors. Make the necessary corrections to the folder structure and re-run the validation.

5. After successful validation, the status of BIDS compliant is displayed in the Explorer until the next validation.
