pyprep is a python implementation of the Preprocessing Pipeline (PREP) for EEG data, working with MNE-Python for EEG data processing and analysis. Also contains a function to detect outlier epochs inspired by the FASTER algorithm.

ALPHA SOFTWARE. This package is currently in its early stages of iteration. It may change both its internals or its user-facing API in the near future. Any feedback and ideas on how to improve either of these is more than welcome! Use this software at your own risk.


pyprep requires Python version 3.6 or higher to run properly. We recommend to run pyprep in a dedicated virtual environment (using e.g., conda).

For installing the stable version of pyprep, simply call pip install pyprep. This should install dependencies automatically, which are defined in the setup.cfg file in the options.install_requires section.

For installation of the development version use:

git clone
cd pyprep
pip install -r requirements-dev.txt
pre-commit install
pip install -e .
