CHARMM is a versatile molecular modeling and simulation program designed to provide broad application to the simulation of many-particle systems, and includes a comprehensive set of force fields to simulate biomolecules, such as proteins, nucleic acids, carbohydrates, lipids, their assemblies, and the small molecules that interact with these targets. CHARMM runs on a variety of UNIX-compatible platforms, with optional graphical output. For more information on the CHARMM program, its capabilities and documentation, visit www.charmm.org.
