Software Downloads

Axiom Discovery is making its Molecule Viewer (Lite Edition) available as a free download.  Molecule Viewer is a Windows application that works in a similar way to the Windows Picture and Fax Viewer that is part of the Microsoft Windows operating system. 


Molecule Viewer allows users to view molecular structures stored in a wide variety of file formats including Brookhaven PDB, Alchemy, MDL, Gaussian, MOPAC, etc by simply right-clicking on the file in Windows Explorer and selecting the "Preview" command.

Features include:

  • view structures in traditional renderings such as ball and stick
  • view proteins as ribbons, cartoons, barrels and tubes
  • view solvent accessible surfaces
  • view molecular orbitals and iso-density surfaces saved in Axiom Discovery workspace files
  • animation of normal modes (one randomly selected)
  • supports many common file formats include PDB
  • print images direct to a printer
  • edit structures in IDEaTM  and Molecular ExplorerTM (requires one of these to be installed)
  • OpenGL based rendering with full control over how the image is rendered including background colors and gradients, projection, anti-aliasing, etc.

The advanced version of the Molecule Viewer application provides additional features such as:

  • visualization of electronic structure information in Gaussian files, MOPAC files, Games-US files, etc.
  • Molecular orbitals, iso-density and iso-potential surfaces can be viewed without requiring Gaussian or MOPAC
  • advanced property mapped surfaces
  • contact and Connolly surfaces in addition to solvent accessible surfaces
  • visualization of dipole moments and atomic charges for both ground state and excited states
  • animation of all normal modes and reaction paths
  • many more visualization features found in high-end molecular modeling packages
