Eelbrain is actively developed and maintained by Christian Brodbeck at the Computational sensorimotor systems lab at University of Maryland, College Park.

Eelbrain is fully open-source and new contributions are welcome on GitHub. Suggestions can be raised as issues, and modifications can be made as pull requests into the master branch.

The Development Version

The Eelbrain source code is hosted on GitHub. Development takes place on the master branch, while release versions are maintained on branches called r/0.26 etc. For further information on working with GitHub see GitHub’s instructions.

Installing the development version requires the presence of a compiler. On macOS, make sure Xcode is installed (open it once to accept the license agreement). Windows will indicate any needed files when the install command is run.

After cloning the repository, the development version can be installed by running, from the Eelbrain repository’s root directory:

$ python develop

On macOS, the $ eelbrain shell script to run iPython with the framework build is not installed properly by; in order to fix this, run:

$ ./fix-bin

In Python, you can make sure that you are working with the development version:

>>> import eelbrain
>>> eelbrain.__version__

To switch back to the release version use $ pip uninstall eelbrain.

Building with Conda

To build Eelbrain with conda, make sure that conda-build is installed. Then, from Eelbrain/conda run:

$ conda build eelbrain

After building successfully, the build can be installed with:

$ conda install --use-local eelbrain

Useful tools:


Tests for individual modules are included in folders called tests, usually on the same level as the module. To run all tests, run $ make test from the Eelbrain project directory. On macOS, tests needs to run with the framework build of Python; if you get a corresponding error, run $ ./fix-bin pytest from the Eelbrain repository root.
