• data contains all data used, organized per dataset (see above). For every dataset a [dataset]-intervals.txt file is produced that contains one interval per line, measured in seconds. This file can easily be read into Python using NumPy's np.loadtxt function. Where possible, the original data has been included in a original-data directory.
• notebooks contains all Jupyter notebooks used to preprocess datasets and generate the visualizations.
• figures contains the figures.
• rhythmplot contains the Python code needed to generate rhythm triangle plots. It also includes some code for working with rhythmic motifs.

You can find the Python version used in .python-version and all dependencies are listed in requirements.txt. If you use pyenv and venv to manage python versions and virtual environments, do the following:

# Install the right python version
pyenv install | cat .python-version

# Create a virtual environment
python -m venv env

# Activate the environment
source env/bin/activate

# Install dependencies
pip install -r requirements.txt
