gmx - molecular dynamics simulation suite
gmx [-[no]h] [-[no]quiet] [-[no]version] [-[no]copyright] [-nice <int>] [-[no]backup]
GROMACS is a full-featured suite of programs to perform molecular dynamics simulations, i.e., to simulate the behavior of systems with hundreds to millions of particles using Newtonian equations of motion. It is primarily used for research on proteins, lipids, and polymers, but can be applied to a wide variety of chemical and biological research questions.
