CCL: Jmol script for plotting 3D vectors on molecules: jvec2jmol

[Mikael Johansson <mikael.johansson,+,iki.fi>]

 Hello All,
 Just in case someone happens to find it useful:
I couldn't find a quick and simple way to visualize vector data
 together
 with molecules, especially in 3D; while the failure might very well be
 due
 to a deficiency in googling skill, I made an attempt at creating a
 tool.
 If you have a file wih vector data in six columns, in the simple format
   x.coord y.coord z.coord d.x d.y d.z
the jvec2jmol script transform the vectors into Jmol script form for
 quick
 visualization. At simplest, the syntax would be:
   jvec2jmol.py data.txt data.jmol;  jmol -s data.jmol
You will probably want to display some molecule as well, of course.
 The
 default values of the script are biased towards displaying magnetically
 induced current vectors, but are easily adjustable.
jvec2jmol has a few colour gradient options, and a rudimentary
 understanding of translucency. It even comes with a quick but not
 necessarily dirty mini-tutorial.
The script can be downloaded here; the .tar.gz file contains some
 simple
 examples:

 Of course, comments, bug reports, etc, are welcome.
 Cheers,
     Mikael J.
