Several Unix scripts are provided here for viewing
CIF data and using Xtal (3.6 or GX) or Rasmol for displaying
molecular structure. One of the scripts couples this facility to
Netscape for the interactive viewing of CIF data downloaded from a
The molecular graphics program PIG now generates a
POV-Ray file and attempts to automatically spawn a POV-Ray process,
when requested. The .pov file produced can be run through POV-Ray
as a standalone process to produce .ppm or .tga images of
sufficient resolution for including in publications.
At exit from the Xtal molecular graphics program PIG,
both a PDB file of the current asymmetric unit and an .xyz file of
all viewable atom coordinates are created. Both of these files can
be read and displayed by RasMol which can be used as a basis for
conversion to several other molecular description formats. The .xyz
file in particular is useful for introducing symmetry related atom
sites to the largely symmetry-ignorant RasMol.
