Instructions

1. Download or pull the whole repository into a selected working directory.
2. Run the Juptyer notebook 'Example' to verify that the model components (pyEW) are correctly used within the notebooks.
3. Change the parameters in the file 'Example' to run specific simulations for different scenarios.
4. For the Jupyter notebooks of the model-experiment comparison, define the selected base directory in the first cell of each notebook.
