Software Used in Molecular Modeling and Molecular Dynamics

AMBER (UNIX; proprietary) at Peter A. Kollman's research group at the University of California San Francisco (Updated 5/22/99).
Description: AMBER refers to two things: a molecular mechanical force field for the simulation of biomolecules (which is in general use in a variety of simulation programs); and a package of molecular simulation programs which includes source code and demos.(Updated 5/22/99).
new.GIF (3043 bytes)AMMP (Unix, Linux, and PC; Free Downloadable Software) is a modern full-featured molecular mechanics, dynamics and modeling program. It can manipulate both small molecules and macromolecules including proteins, nucleic acids and other polymers. This software is found at Structural Biology at Jefferson and the Kimmel Cancer Center (Updated 5/22/99).
CHARMM Homepage (UNIX; License Required) by Martin Karplus's group at Harvard University. Charmm has been integrated into the popular molecular modeling software package, QUANTA, of Molecular Simulations Inc. (MSI) (Updated 5/22/99)
CHARMM Commands 
Description: CHARMm combines standard minimization and dynamics capabilities with expert features including free energy perturbation (FEP), correlation analysis and combined quantum and molecular mechanics (QM/MM) methods. Simulations provide insight into molecular-level structure, interactions, and energetics (Updatd 5/22/99).
new.GIF (3043 bytes)Chem2Pac is intended to be a kind of computational chemistry integrator, which has a multiple document interface, a molecular rendering utility, and allows the manipulation of various files (Updated 6/16/99).

GAMESS Home Page (Unix, VMS, MVS, VM, Mac, or PC; free downloadable Software) for doing ab initio calculations at Ames Laboratory/Iowa State University (Updated 5/22/99).
Description: GAMESS can compute wavefunctions ranging from RHF, ROHF, UHF, GVB, and MCSCF, with CI and MP2 energy corrections available for some of these (Updated 5/22/99).
new.GIF (3043 bytes)GROMACS (Unix, and PC (in the future), free downloadable for non-commercial users) is a useful suite of molecular modeling utilities available at Chemistry department University of Groningen (Updated 5/22/99).
MEPSIM distribution (Code obtainable through email; Website currently under construction) for Molecular Electrostatic Potential SIMilarity Analysis (Updated 5/22/99)
Description: New features of the program will include the possibility of performing GAMESS and GRID calculations within the package, taking profit of the MEPSIM modules (Updated 5/22/99).
MOLGEN (MSDOS; free downloadable) automatic structure elucidation (FTP site)(Updated 5/22/99)
Description: This software allows the user to do various calculations (i.e. HOMO, LUMO, potential) on small molecules (Updated 5/22/99).
MOLSCAT (UNIX; free downloadble) is a code for quantum mechanical (coupled channel) solution of the nonreactive molecular scattering problem (Updated 5/22/99).

Documentation
Description: MolScript is a program for creating schematic or detailed molecular graphics images from molecular 3D coordinates, usually,
but not exclusively, protein structures (Updated 5/22/99).
new.GIF (3043 bytes)MMTK (UNIX (Requires Python); free downloadable) Molecular Modelling Toolkit (MMTK) is a program library for molecular modelling applications at Theoretical biophysics at the CBM (Updated 5/22/99).
Description: MMTK provides researchers, especially those working on the development of new simulation and modelling methods, with a code basis that can be easily extended and modified to deal with standard and non-standard problems in molecular modelling (Updated 5/22/99).
NAMD Home Page (UNIX; free downloadable, but registration required ) is a parallel, object-oriented molecular dynamics code designed for high- performance simulation of large biomolecular systems at the Theoretical Biophysics Group of University of Illinois at Urbana. (Updated 5/22/99)
TINKER Molecular Modeling Package, (PC; free downloadable) it is a program that accepts a variety of different parameter files from a variety of different molecular dynamics packages, including AMBER, and CHARMM (Note: Trouble connecting to server 5/22/99, Updated 5/22/99).
Molda is a Graphics interface for Tinker.  Note: the Tinker server is sometimes down, so in the near future I will try to make copies available to this site. (Updated 5/22/99)
