Notebooks for reproducing all figures and analysis of simulated and single-cell datasets for the meK-Means paper. All saved/processed data used for analysis can be found on CaltechData. Figure created with BioRender.com.

For notebooks that run on Google Colab, you will see the Colab link included at the top of the notebook. Just click on the symbol.

An introduction to using Google Colab can be found here. Briefly, run each code cell by selecting the cell and executing Command/Ctrl+Enter.

#To install meK-Means

pip install monod

import monod
from monod import mminference #Function implementing meK-Means algorithm

meK-Means utilizes the Monod package for single-cell, CME-based inference.
