hello,

I have created a new resource for Jmol, Rasmol, and Chime developers
called Color Gradients.  you can use it to create script commands that
apply a gradient color scheme to your molecule of choice.  this is
similar to the 'color group' command already present in Rasmol, but with
some improvements:

1. choose from among four different gradient styles (rainbow,
blue-white-red, black-white, or white-black).

2. create gradients that apply to a single chain, span multiple chains,
or apply separately to each chain of a multi-chain structure.  up to
four chains are supported at this time.


Color Gradients is comptible with Jmol, Rasmol, and Chime, and is
available here:

<http://www.molvisions.com/resources/color_gradients/>


(you can also access it under the Resources menu at my home page,
<http://www.molvisions.com/>.)  it will run in any Web browser; not even
javascript is required.  ;-)

to use Color Gradients, you will need to enter the chain designators,
and the starting and ending residue numbers for each chain.  the output
is a simple html file containing your script commands, from which you
can select all, copy, and paste into your spt file (or an empty text
file).

plans for the future include allowing a pdb file to be uploaded
directly, to read chains and residues from the file itself, and other
output and command formatting options.


if anyone has any suggestions for improving this resource, or if it
doesn't work as expected, please feel free to send me email (offlist, if
you prefer).


regards,

tim
