Patients stratification with Graph-regularized Non-negative Matrix Factorization (GNMF) in Python.

## Dependencies
The minimum required dependencies to run the software are:
- Python >= 3.4
- NumPy >= 1.6
- SciPy >= 0.7.2
- matplotlib >= 0.98.4
- scikit-learn >= 0.19
- pandas >= 0.1
- tqdm>=4.15.0

If you want to launch Reproducibility project by Jupyter Notebook, you will also need:
- ipython>=1.1.0
- jupyter


## Reproducibility
To reproduce the figure 3 of [our paper about reproducibility in bioinformatics](https://www.biorxiv.org/content/early/2017/10/31/143503), you have two options:
1. Follow the Jupyter Notebook [reproducibility.ipynb](reproducibility/reproducibility.ipynb)
2. Build & run the [Docker](http://docker.com) container with:
```
~$ mkdir <your_output_folder_outside_stratipy_folder>
~$ docker build -t repro .
~$ docker run -v /absolute/path/of/<your_output_folder_outside_stratipy_folder>:/reproducibility/reproducibility_output repro
```
**For Windows or Mac users:** total runtime memory of Docker is fixed to 2 GB by default. In order to launch this project, you have to increase this limit (approximately 7 GB):
- [Windows setting](https://docs.docker.com/docker-for-windows/#advanced)
- [Mac setting](https://docs.docker.com/docker-for-mac/#cpus)
