MacMolPlt

by Brett Bode

wxMacMolPlt is an open-source, cross-platform (Mac OS X, Linux and Windows) gui for preparing, submitting and visualizing input and output for the GAMESS quantum chemistry package. Features include a graphical molecule builder, GAMESS input generation, animation of output and visualization of molecules, normal modes, orbitals and other properties.

Key Features:

• Input using:
  • MolPlt file format punched out by GAMESS
  • by pasting in Cartesian coordinates from any GAMESS or Gaussian log file
  • any GAMESS input, log or irc file
  • Xmol style XYZ file
  • MolDen format files
  • Protein Data Bank (pdb) file
  • Chemical Markup Language (CML) files
  • Build graphically with an interactive molecule editor
  • Build by hand using cartesian or Z-Matrix style internal coordinates
• 3D display of structure and Normal mode
• Animation of Normal modes.
• 3D real-time rotation and translation under mouse control
• Calculation of any Z-matrix parameter
• Visually measure/display distances, angles and dihedrals.
• Automated creation of Linear Least Motion (LLM) paths
• 2D and 3D calculation and display of:
  • Molecular orbitals (AO's, MO's, or LMO's)
  • Total Electron Density
  • Density differences
  • Molecular Electrostatic Potentials (MEPMaps)
• Basic input file generator for GAMESS
• OpenGL used for high-quality 3D rendering
• Support for molecular symmetry
  • Generate symmetry dependant atoms
  • Determine symmetry unique atoms
  • Automatically determine the list of supported point groups for a set of coordinates.
  • Rotate coordinates into the proper principle orientation and symmetrize the coordinates
  • Display symmetry operators for many point groups
  • Edit while enforcing symmetry
• Publication quality output (color or black and white) via direct printing or Copy and Paste into another Application.
• Output in a variety of forms including Windows bitmap, JPEG, GIF, PNG, CML, XMol XYZ, MDL molfile, animated GIF, Flash Movies and QuickTime movies.

If you like the program send me comments about what you like and what you would like to see in future versions. If you don't like the program then chuck it, just remember the price was right!

Brett Bode is the primary developer of MacMolPlt with past contributions from several talented individuals including Chris Johnson, Song Li, and Steven Schulteis. Please see the contributors list on GitHub for the most recent contributions.

Requirements for Linux systems:

OpenGL

wxWidgets install with OpenGL enabled. (either from a vendor supplied library or source install).

Requirements for MacOS X:

10.11 and newer for the 64 bit (x86_64 or ARM) version.

10.4 and newer for the 32 bit build available for v7.7. No longer built by default.

Requirements for Windows:

The 64 bit version is built on Windows 10, but should work on all 64 bit Windows OS's

The 32 bit version is built on Windows 7, but is believed to work correctly on older Windows versions such as XP. (depricated as of v7.7.1)
