BIDS for MATLAB / Octave

Build Status Binder

This repository aims at centralising MATLAB/Octave tools to interact with datasets conforming to the BIDS (Brain Imaging Data Structure) format.

For more information about BIDS, visit

See also PyBIDS for Python and the BIDS Starter Kit.


Download this repository and add it to your MATLAB/Octave path.


If your version of MATLAB/Octave does not support JSON natively, please also install SPM12 or JSONio.


BIDS = bids.layout('/home/data/ds000117');
bids.query(BIDS, 'subjects')

A tutorial is available as a Jupyter Notebook and can be run interactively via Binder.


BIDS-MATLAB works with MATLAB R2014a or newer, or Octave 4.2.2 or newer. (It may also work with older versions, but those are not actively supported.)

If you are using MATLAB R2016b or newer, nothing else needs to be installed.

If you are using MATLAB R2016a or older, or using Octave, you need to install a supported JSON library for your MATLAB or Octave. This can be any of:


Starting point was spm_BIDS.m from SPM12 (documentation) reformatted in a +bids package with dependencies to other SPM functions removed.

Other tools (MATLAB only)
