====== 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 [[https://bids-specification.readthedocs.io/en/stable/appendices/entity-table.html|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 [[:tools:fmriprep]], [[:tools:qsiprep]], freesurfer bids, bids2nda. See https://bids-apps.neuroimaging.io/
