What is AMBER?
AMBER (Assisted Model Building with Energy Refinement) is a package of programs for molecular dynamics simulations of proteins and nucleic acids. AMBER is distributed in two parts: AmberTools and Amber. AmberTools is a collection of freely available programs for biomolecular simulation and analysis. Amber is centered around the pmemd simulations program and is under a restrictive license.
