Contributor Guide

Thanks for your interest in contributing to biopeaks! Please have a look at the code of conduct.

Ways to contribute

Reporting bugs or asking questions

Please report bugs or ask questions by opening an issue in the biopeaks repository.

Improve documentation, tests, or code

If you plan to contribute relatively large changes, please open an issue in the biopeaks repository before you start working on your contribution. This way we can discuss your plans before you start writing/coding.

You can follow these steps to contribute documentation, tests, or code:

  1. Fork the biopeaks repository.
  2. Add a topic branch with a descriptive name to your fork. For example, if you want to contribute an improvement to the documentation you could call the topic branch improve-docs.
  3. Install biopeaks in development mode:
    1. Make a local clone of your fork.
    2. Open the clone in the project’s devcontainer.
  4. Implement your contribution in the topic branch, following the conventions.
  5. Make a pull request from the topic branch on your fork to the dev branch of the biopeaks repository.
  6. Once all CI tests pass and your changes have been reviewed, your PR will be merged and you’re a contributor!

Conventions

General

Code style

Architecture

The GUI is structured according to a variant of the model-view-controller architecture. To understand the relationship of the model, view, and controller have a look at how each of them is instantiated in __main__.py. For example, the view has references to the model as well as the controller, whereas the model has no reference to any of the other components of the architecture (i.e., the model is agnostic to the view and controller).

Documentation

The documentation is hosted on GitHub pages, a static website associated with the biopeaks repository: https://jancbrammer.github.io/biopeaks/. It is automatically build from the /docs folder in the root of the biopeaks repository. The website is re-build every very time the content of /docs changes on the main branch (pushes, merged pull requests). /docs includes an index.md file that constitutes the “landing page”. It contains links to all other parts of the documentation. The layout of the website is defined in /docs/layouts. For additional information, head over to the GitHub pages documentation.

Tests

The OpenSignals test data have been recorded with
software: opensignals v2.0.0, 20190805
hardware: BITalino (r)evolution (firmware 1281)

The EDF test data have been downloaded from https://www.teuniz.net/edf_bdf_testfiles/

All test data are part of the biopeaks installation and do not have to be downloaded.

Please make sure to have pytest as well as pytest-qt installed before running the tests.

The tests can then be run in the test directory with pytest:

pytest -v

Algorithm benchmarks

ECG

To validate the performance of the ECG peak detector heart.ecg_peaks(), please install the wfdb and aiohttp.

You can then run the benchmark_ECG_stream script in the benchmarks folder. The script streams ECG and annotation files from the Glasgow University Database (GUDB). You can select an experiment, ECG channel, and annotation file.

Alternatively, you can download the GUDB and run the benchmark_ECG_local script in the benchmarks folder. In the script, replace the data_dir with your local directory (see comments in the script).

PPG

To validate the performance of the PPG peak detector heart.ppg_peaks() please download the Capnobase IEEE TBME benchmark dataset and install wfdb and h5py.

You can then run the benchmark_PPG_local script in the benchmarks folder. In the script, replace the data_dir with your local directory (see comments in the script).
