The Hyperscanning Python Pipeline.

HyPyP 🐍〰️🐍

The Hyperscanning Python Pipeline

⚠️ This software is in beta and thus should be considered with caution. While we have done our best to test all the functionalities, there is no guarantee that the pipeline is entirely bug-free.

📖 See our paper for more explanation and our plan for upcoming functionalities (aka Roadmap).

🤝 If you want to help you can submit bugs and suggestions of enhancements in our Github Issues section.

🤓 For the motivated contributors, you can even help directly in the development of HyPyP. You will need to install uv (see section below).

Installation

pip install HyPyP

Documentation

HyPyP documentation of all the API functions is available online at hypyp.readthedocs.io

For getting started with HyPyP, we have designed a little walkthrough: getting_started.ipynb

Developer Installation (uv)

To develop HyPyP, we recommend using uv. Follow these steps:

1. Install uv:

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# or with pip
pip install uv

2. Clone the Repository:

git clone [e-mail]:ppsp-team/HyPyP.git
cd HyPyP

3. Install Dependencies:

uv sync --group dev

4. Launch Jupyter Lab to Run Notebooks:

uv run jupyter lab

Optional extras:

# Shiny dashboards
uv sync --group dev --extra shiny

# Numba optimization backend (CPU JIT)
uv sync --group dev --extra numba

# PyTorch optimization backend (GPU/MPS)
uv sync --group dev --extra torch

VS Code Integration

uv creates a .venv directory in the project root by default. VS Code should auto-detect it. If not, point the Python interpreter to .venv/bin/python.

Child Head Visualization

As of version 0.5.0b5, hypyp now supports visualization of parent-child or adult-child hyperscanning data. This allows for properly scaled and positioned head models when analyzing data from participants of different ages.

To use this functionality, simply set the children=True parameter in visualization functions and specify which participant is the child using the child_head parameter.

Example:

# Visualize parent-child data (epo1 = parent, epo2 = child)
viz_3D_inter(epo1, epo2, C, threshold=0.95, steps=10, children=True, child_head=True)
