Projects / Viewmol


Viewmol is a program for building and editing molecules as well as for the visualization of outputs from quantum chemical and molecular mechanics programs. Currently supported are Gaussian 9x, Gamess, Discover, DMol/DSolid/DMol3, Gulp, Mopac, Turbomole, and PDB files. Properties visualized include geometry (with various drawing modes), vibration (animated or with arrows), optimization history/MD trajectories, MO energy level diagram, MOs, basis functions, and electron density. Drawings can be saved as TIFF, HPGL, Postscript, and input files for Rayshade. Viewmol has an embedded Python interpreter for automation. The program is language independent and currently "speaks" English, French, German, Russian, or Spanish.

Recent releases

  •  16 Nov 2004 20:05

    Release Notes: This release adds support for Gaussian 03 outputs, (partial) support for Turkish, and a delay option in resources to control animation speed. The crash on saving images has been fixed. The dependency on has been removed.

    •  12 Nov 2003 16:45

      Release Notes: Open shells in Gamess and Turbomole outputs are now supported. Periodic wave functions are also supported. The ability to read grid data and visualize them, to read PQS outputs, to read the Bravais matrix for defining unit cells, to generate input files for Gaussian, and the ability to save drawings as PNG files and Postscript bitmaps have been added. Scripts to set atom colors through the user interface and to perform UFF geometry optimization using Turbomole's UFF module have been included. Python scripts can now install themselves in a menu. Mac OS X is now supported as platform.

      •  08 Jan 2001 16:02

        Release Notes: This release includes an embedded Python interpreter, calculation of thermodynamic properties for molecules and reactions between them, display of Miller planes for solids, reworked moving of molecules (no more molecule fixed coordinate system), changes to the OpenGL/X Windows integration, a lot of bug fixes, and an input filter for Gamess. The user interface has been tranlated into Spanish.

        •  03 Jun 1999 08:30

          Release Notes: This version fixes bugs discovered since version 2.2 and adds the ability to change Van der Waals radii (and therefore connectivity) of a molecule on the fly. Optmization histories/MD trajectories can now be animated, bindings and icons to KDE aware of molecular modeling formats have also been provided.
