Amber Usage

Amber is a package of molecular simulations programs and associated molecular mechanics force fields used for the simulations of biomolecules. The current version is Amber18 built with the new AmberTools18 .

The amber website, http://ambermd.org, includes program descriptions, manuals, FAQ, as well as tutorials to get started with amber. In addition there is an Amber Mail Reflector that you can subscribe to that is a useful forum for the discussion of the use of the software.

Beginning users are strongly encouraged to go through the AMBER tutorials that come with each distribution. They can also be easily accessed at http://ambermd.org/tutorials

There is now a single build that runs on all clusters.  Both serial and MPI versions exist for the cpptraj, mdgx, MMPBSA.py,sander, sander.LES, pmemd and pmemd.amoeba programs; cuda versions also exist for pmemd and cpptraj.

  • Version: Amber18
