The goal of these tools is to interpret experimental data and provide insight into complex biological systems using physics and statistical mechanics. Potential uses are for analyzing simulation results and building larger models from simulation data and preparing for runs using OpenMM and running massive calculation in parallel.

The methods are focused on computer simulations with enhanced sampling techniques. Monte Carlo and Molecular Dynamics simulations written from the ground up and using the OpenMM toolkit (LGPL C++ library)
