Datasets

Here are some links to BIDS compliant data. Sourcedata (pre-BIDS) are sometimes also available, these can be used to just see (or to build tutorials) of how source data are converted to BIDS.

BIDS examples with data files

OpenNeuro: If you're looking for full data files to run the validator on or simply compare to your own bidsified data try searching here. Datasets here are (by and large) publicly available and conform to BIDS.

Brainhack Western 2018 dataset

• sourcedata: ds001
• rawdata: ds001_BIDS

Mother of unification studies

A 204-subject multimodal (MEG, MRI, fMRI) dataset to study language processing.
