Why PhysioZoo?

  • Data visualization: graphical user interface which enables HRV analysis and data visualization without writing any code.

  • Reproducibility of research: Human readable configuration files which contain all the parameters of the peak detectors, preprocessing routines and HRV measures. This file is self containing and ensure research can be reproduced using this configuration file and the original data.

  • Algorithmic toolbox: Completely scriptable for embedding into your custom processing code.

  • Open-source collaborative platform: Both the source code and documentation are not only freely available, they’re also easy to modify and update using git and GitHub.

How to contribute?

The PhysioZoo project is dynamic and so novel contributions are welcomed. You can contribute by:

  • Fork it fork the repository on the project’s main page

  • Create a pull request contribute algorithms and improvements to the PhysioZoo toolbox

  • Bugs! In case you in encounter a bug and cannot figure out the solution, please have a look at the issues page and don’t hesitate to open a new issue if you can’t find an answer.

  • Pitch in your new ideas for future releases by suggesting an enhancement.

Benefits of Contributing

Collaborative research has various benefits, here are some of those:

  • Enable other researchers to contribute, debug and build on your work
  • Advertise your research, published algorithms are linked in the documentation
  • Ensure reproducibility of your results
