 The OpenScope Databook is a community project. It aims to serve as a collection of contributed analyses from many different experts and to include a comprehensive set of useful and reproducible analyses. Contributors are added to the authors list and have an opportunity to share their figures, results, and datasets through their notebooks in the Databook. Together the project can grow and continue to shape the growing reproducible neuroscience ecosystem.

 Then the environment must be set up. You may set up a conda environment if you don't want to interfere with your local environment. After installing conda, this can be done with the commands `conda create --name databook python=3.11` followed by `activate databook` (Windows) or `source activate databook` (Mac/Linux). Within or without the conda environment, the dependencies for the databook can be installed by navigating to the openscope_databook directory and running `pip install -e . --user`.
