BIDS

The Brain Imaging Data Structure is a specification for how to organize and name imaging files. The homepage is https://bids-specification.readthedocs.io/. The entities table is a dense and complete description of the information contained in BIDS.

Files are organized with names that have _ separated key-value pairs within “data type” directories (eg. anat) and end with a “modality suffix” label (e.g. T1w).

An interactive name builder for the upstream ReproIn standard, https://npacore.github.io/reproin-namer/, many be useful.

BIDS organization is a prerequisite for many tools, including fmriprep, qsiprep, freesurfer bids, bids2nda. See https://bids-apps.neuroimaging.io/
