Neuroimaging experiments result in complicated data that can be arranged in many different ways. So far there is no consensus how to organize and share data obtained in neuroimaging experiments. Even two researchers working in the same lab can opt to arrange their data in a different way. Lack of consensus (or a standard) leads to misunderstandings and time wasted on rearranging data or rewriting scripts expecting certain structure. Here we describe a simple and easy to adopt way of organizing neuroimaging and behavioral data. By using this standard you will benefit in the following ways:
BIDS is heavily inspired by the format used internally by OpenfMRI.org. While working on BIDS we consulted many neuroscientists to make sure it covers most common experiments, but at the same time is intuitive and easy to adopt. The specification is intentionally based simple file formats and folder structures to reflect current lab practices and make it accessible to wide range of scientists coming from different backgrounds.
Software currently supporting BIDS:
A good introduction to the BIDS standard can be found in the paper published in Nature Scientific Data.
A description of how to build containerized apps supporting BIDS inputs can be found in the paper published in PLOS Computational Biology.
There are many different experiments and data types used in cognitive and clinical neuroimaging. Help us make BIDS better by commenting on the draft specificationComment on the BIDS draft
