Amber is a suite of biomolecular simulation programs. It began in
the late 1970's, and is
maintained by an active develpment community; see our history page and our
contributors page for more information.
The term "Amber" refers to two things. First, it is a set of molecular mechanical
force fields for the simulation of biomolecules
(these force fields are in the public domain, and are used in a variety of
simulation programs). Second, it is a package of
molecular simulation programs which includes source code and demos.
Amber is distributed in two parts:
Amber18. You can use AmberTools18 without
Amber18, but not vice versa. See the Download
Amber link for information on how to download the code.
Amber is developed in an active collaboration of David Case at Rutgers
Cheatham at the University of Utah, Ken Merz at Michigan State
Roitberg at the University of Florida, Carlos
Simmerling at SUNY-Stony Brook, Ray Luo at UC Irvine, Junmei Wang at
the University of Pittsburgh, Ross
Walker at GSK, and many
others. Amber was originally developed under the leadership of Peter
