This repository contains the code behind ExPheWas. A thorough description of the project can be found either in the project's documentation or in the manuscript.

The exphewas python package can be installed (e.g. using pip install .. Once this is done, a command-line utility will be available that offers various housekeeping utilities like data loading or database initialization.
The code for the frontend is in the frontend directory. The command npm run build can be used from that directory to build the javascript from the frontend. The code for all D3.js graphs can be found there.
Configuration only requires a database string for SQLAlchemy and the path where the frontend gets built.
