The main difference between Amber and AmberTools is that AmberTools does not include Sander. AMBER software is used to investigate and simulate biological systems.ĪmberTools consists of several independent software packages such as NAB, Antechamber, LEaP, pbsa, ptraj.

Amber22 Assisted Model Building with Energy Refinement is a computational chemistry software that is developed and used to simulate the molecular dynamics of multi-particle systems based on Newton’s equations of motion. Amber22 and AmberTools22 (2022) version software download it is a molecular dynamics simulation software in computational chemistry.
