**Full Changelog**: https://github.com/BSEL-UC3M/pMoSS/compare/v2.0...v2.1

- The code reproduces previous work using the `pmoss` pypi package.
- The code has been restructured.
- All the dependencies and the operability remain the same

The current version of the code produces two different sets of estimated p-values. The folder data.zip contains them:
- p-values for the morphology changes with the increase of cellular age.
- p-values for the morphology changes in cancer cells and their protrusions after being treated with Taxol.

To avoid heavy computations and make a quick test of the code, download the data. Then, place it into the folder of the cloned repository, so the links in the notebooks work properly. Otherwise, change the links in the notebooks.
