Not quite. In Molscript, if you recall, you do something like this, for
a strand:

  set planecolour ..... ;
  strand from 10 to 20 ;

The whole strand is then the colour you have specified. Raster3D will allow
you to generate ribbons from your coordinates, with varying colours, but
you cannot get strands with arrow heads like Molscript does.  Another
drawback with using Raster3D is that it produces atrocious-looking
bitmapped postscript (this is really postscript's fault, not Raster3D's),
so if you use it, you are better off taking photos from the screen (which
can give really spectacular results). Rasmol/raswin (at least in it's PC
version) produces vector postscript which may give good results, but I
haven't got around to investigating this yet. You can get the latest
versions of rasmol/raswin by anonymous ftp from .

Good luck,
