AMBER

Description

Amber website  

Amber is a suite of biomolecular simulation programs. 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: AmberTools24 and Amber24. 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 University, Tom Cheatham at the University of Utah, Ray Luo at UC Irvine, Ken Merz at Michigan State University, Maria Nagan at Stony Brook, Dan Roe at NIH, Adrian Roitberg at the University of Florida, Carlos Simmerling at Stony Brook, Junmei Wang at the University of Pittsburgh, Darrin York at Rutgers University, and many others. Amber was originally developed under the leadership of Peter Kollman.

Required Modules

For more details on specific modules required for different versions of AMBER, run module spider amber. We currently support amber/24 (with cuda/12.4.1 openmpi/4.1.6 and gcc/12.2.0). Note that the Amber/24 (and Amber in general) is provided to HiPerGator users by the courtesy of Prof. Adrian Roitberg. Amber users are encouraged to register with Amber by downloading FREE version from https://ambermd.org/GetAmber.php. Amber developers appreciate the courtesy.
