AmberTools18 is now available!

AmberTools consists of several independently developed packages that work well by themselves, and with Amber itself. The suite can also be used to carry out complete molecular dynamics simulations, with either explicit water or generalized Born solvent models.

The AmberTools suite is free of charge, and its components are mostly released under the GNU General Public License (GPL). A few components are included that are in the public domain or which have other, open-source, licenses. The sander program now has the LGPL license.

Overview of AmberTools18

AmberTools18 (released on April 17, 2018) consists of the following major codes:

  • NAB/sff: a program build molecules, run MD or apply distance geometry restraints using generalized Born, Poisson-Boltzmann or 3D-RISM implicit solvent models
  • antechamber and MCPB: programs to create force fields for general organic molecules and metal centers
  • tleap and parmed: basic preparatory tools for Amber simulations
  • sqm: semiempirical and DFTB quantum chemistry program
  • pbsa: performs numerical solutions to Poisson-Boltzmann models
  • 3D-RISM: solves integral equation models for solvation
  • sander: workhorse program for molecular dynamics simulations
  • mdgx: a program for pushing the boundaries of Amber MD, primarily through parameter fitting. Also includes customizable virtual sites and explicit solvent MD capabilities.
  • cpptraj and pytraj: tools for analyzing structure and dynamics in trajectories
  • MMPBSA.py and amberlite: energy-based analyses of MD trajectories

Among the new features:

  • CUDA-enabled

    pbsa

    solver; extensions for membrane modeling with PB
  • lambda-dynamics method for constant pH simulations
  • packmol_memgen

    tool for building lipids and bilayers
  • New ("middle") integration algorithms in

    sander

  • Build tools based on CMake
  • Continued updates and extensions to

    cpptraj
