Qmol An OpenGL based molecular viewer for Windows
Qmol is a program for viewing molecular structures and
animating molecular trajectories. Originally based on the molview demo
program by Mark Kilgard (from his book, Programming OpenGL
for the X Window System) and inspired by the Xmol program. Qmol
is similar to programs like VMD , MolMol ,
weblab, Swiss-Pdb Viewer, MolScript, RasMol, gOpenMol and
ICM, but opts for fast, high quality
rendering of molecules with an easy to use user interface. It supports the
following:
| Molecular Display Options |
Wire frame, Stick figure, Ball and stick, Point, Space-filling,
Solid and Flat ribbon, Trace and Tube
Display of multiple molecular models (as used in NMR)
Animate molecular trajectories
Dynamic modification of the color scheme (including
color-by-element, color-by-atom-number, color-by-residue-number,
color-by-temperature, color-by-occupancy and New:
color-by-residue-index)
Dynamic lighting
Adjust atomic radii (including radii-by-temperature and
radii-by-occupancy)
Stereo view
User defined clipping plane with rendered sphere/plane intersections
Molecular Surfaces
New: Simultaneously view and independently manipulate an
arbitrary number of molecules. |
| Analysis and Molecular Manipulation |
New: Superimpose two molecules (by rigid body rotation and
translation) with arbitrary atom selection.
New: Interactively compute RMSD between two molecules (with
arbitrary atom selection).
Align all structures in a trajectory against the initial
structure
Interactively measure bond lengths, bond angles and torsion
angles
Dynamically adjust user selected torsion angles
Display atom labels and coordinate axis
Detect and display hydrogen bonds (using the energetic criterion
of Kabsch and Sander). NEW: Intermolecular hydrogen bonds are
determined in "real time".

| Import Formats |
PDB files
Compressed PDB files (using zlib) i.e. *.pdb.gz
Directly query the Protein
Data Bank and display the resulting structure
Paste temperature and occupancy PDB fields from the windows
clipboard |
| Output Formats |
Generate AVI movies from a molecular trajectory
Print to any Windows supported printer and copy images to the
Windows clip board
Export images in BMP, PNG and Postscript (using
vector, not raster, output) |
The main focus of the development is now the Windows platform. Other
programs that may be of interest:

with either 16 bits-per-pixel (bpp) or 24 bpp color depth. Uncompressed
AVI files can be quite large and you may wish to compress them using one
of the "built-in" compression formats or with an external programDownload for Windows Download the
