PyBIDS

PyBIDS is a Python library to centralize interactions with datasets conforming BIDS (Brain Imaging Data Structure) format. For more information about BIDS visit https://bids.neuroimaging.io.

PyBIDS currently supports Python 3 on POSIX operating systems (including Mac OS). Windows is not officially supported, though most PyBIDS functionality will probably work fine.

Installation

PyBIDS is most easily installed from pip. To install the latest official release:

pip install pybids

Or, alternatively via conda:

conda install -c conda-forge pybids

If you want to live on the bleeding edge, you can install from master:

pip install git+https://github.com/bids-standard/pybids.git

Dependencies

PyBIDS has a number of dependencies. The core querying functionality requires only the BIDS-Validator package. However, most other modules require the core Python neuroimaging stack: numpy, scipy, pandas, and nibabel. The reports module additionally requires num2words. By default, all dependencies will be installed with pybids (if they aren't already available).

Usage

Get started by checking out the documentation!

Or you can start at our tutorial! You can run it interactively without installing anything via binder. Click on the link and then navigate to doc/examples/pybids_tutorial.md to explore.

Development and testing

PyBIDS uses tox to manage testing environments and ensure that the same commands can easily be run locally and in CI.

Install tox with:

pip install tox

To run tests with standard, minimal, or pre-release dependencies, use:

tox run -e [full|min|pre]

To run with a specific version, also specify py3X:

tox run -e py311-full

See tox documentation for more detail.
