NAME

       viewmol - a graphical front end for computational chemistry programs

SYNOPSIS

       viewmol

DESCRIPTION

       viewmol  is a graphical front end for computational chemistry programs.  It is able to graphically aid in
       the generation of molecular structures for computations and to visualize  their  results.  The  program's
       capabilities include:

       • Building and editing of molecules

       • Visualization of the geometry of a molecule

       • Tracing of a geometry optimization or a MD trajectory

       • Animation of normal vibrations or to show them as arrows

       • Drawing of IR, Raman, and inelastic neutron scattering spectra

       • Drawing of an MO energy level or density of states diagram

       • Drawing of basis functions, molecular orbitals, and electron densities

       • Display of forces acting on each atom in a certain configuration

       • Display of Miller planes in crystals

       • Calculation of thermodynamic properties for molecules andreactions

       • Drawings generated by viewmol can be saved as TIFF, HPGL, or PostScript files

       • Animations of normal modes can be converted to a video file (MPEG), e. g. for inclusion into World Wide
         Web documents (requires additional programs available on the Internet)

       • Interface  to the freeware ray tracing program RAYSHADE (input file generation and use of RAYSHADE from
         within viewmol)

       • Input and output in a variety of formats, new formats can be added easily by the user viewmol  includes
         a Python interpreter for automation.

       At  present  viewmol  includes  input  filters  for DISCOVER, DMOL, GAMESS, GAUSSIAN 9X, GULP, MOPAC, and
       TURBOMOLE outputs as well as for PDB files (viewmol is therefore suited as a viewer for  structural  data
       on  the  World  Wide  Web). Structures can be saved as MSI car-files, MDL files, and TURBOMOLE coordinate
       files. viewmol's file format has been added to BABEL so that BABEL can serve as an input as  well  as  an
       output filter for coordinates.

       viewmol supports a space ball as input device.

       The  support  programs  for  converting  to and from the various coordinate file types may potentially be
       useful as stand alone utilities. They are split between /usr/share/viewmol (scripts) and /usr/lib/viewmol
       (C binaries), but individual documentation for them is not available.
