See the iPython notebook analysis.ipynb for details on the affinity maturation simulations. Running this notebook requires the Python packages NumPy, pandas, and Matplotlib.

Matlab data and scripts for the molecular dynamics analysis are located in the molecular_dynamics/ folder. See the molecular_dynamics/README.md for details.
