A Public Domain Molecular Modeling Software. Biomolecular calculations made easy. MOIL is a suite of integrated modular (FORTRAN) applications specially designed to help users perform a variety of biomolecular calculations and simulations using molecular mechanic force fields.

Moil supports the usual set of tools for molecular modeling by classical mechanics, including energy calculations, energy minimization, molecular dynamics, and more. Code is available to simulate curve crossing within the Landau Zener model. Moil allows for reasonably straightforward conversion of PDB files to computable datasets (coordinate and energy templates).

Besides "standard" applications MOIL evolves around the research in Ron Elber's laboratory. Examples are the Locally Enhanced Sampling Approach2 and reaction path and long time dynamics algorithms 3 that are based on action optimization. Also included the recently developed Milestoning approach for the calculation of kinetics and thermodynamics along a reaction coordinate4. The integration of a coarse-grained model into moil is yet another new feature of MOIL11.
