"Amber" refers to two things. First, it is a set of molecular mechanical
force fields for the simulation of biomolecules
(these models 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:
Amber16. You can use AmberTools16 without
Amber16, but not vice versa. See this
link for information on how to obtain Amber16.
Amber is developed in an active collaboration of
David Case at Rutgers University,
Tom Cheatham at the
University of Utah, Ken Merz
at Michigan State University,
Adrian 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 UC San Diego, and many others.
Amber was originally developed under the leadership of Peter Kollman.
