another free mol viz pkg



 I just spotted this on bionet.biology.computational. I haven't tried it.

     This posting is to announce the public release of RasMol 2.2 molecular
 graphics visualisation program.  This package has been developed in the
 BRU over the last few years, and the latest version has a significant
 number of improvements over RasMol 2.1. These enhancements include protein
 ribbon diagrams, secondary structure assignment (based on Kabsch and
 Sander's DSSP algorithm), better amino acid classification, DNA hydrogen
 bonding, DNA backbone representations, stick representations of hydrogen
 bonds and disulphide bridges (either between backbone or sidechains), the
 ability to write out selected atoms to a PDB file, support for Alchemy
 format files, colouring of hbonds by their type, compressed PostScript
 output, extended atom expression syntax, increased scroll bar functionality,
 and many more additions (and bug fixes) too numerous to mention. For a
 complete list of modifications (and acknowledgements), refer to the
 distribution ChangeLog.
     RasMol is an X Window System tool intended for the visualisation of
 proteins and nucleic acids. It reads Brookhaven Protein Databank (PDB)
 files and interactively renders them in a variety of formats on either an
 8bit or 24/32bit colour display. The complete source code and user
 documentation for both the UNIX/X11 version and the IBM PC/MS Windows 3.1
 version may be obtained by anonymous ftp from ftp.dcs.ed.ac.uk
 [129.215.160.5] in the directory /pub/rasmol. The UNIX/X11 source code is
 contained in the file RasMol2.tar.Z and the MS Windows source code and
 executable in the file raswin.zip. Both of these files include a slightly
 dated version of the PostScript user reference manual.
     The program is intended for teaching and generating publication
 quality images. The program has both a menu system and a full featured
 command line interface. Different parts and representations of the
 molecule may be coloured or displayed in a number of formats independently.
 Currently supported formats include wireframe, ball and stick, backbone,
 space filling spheres and protein ribbon models. The space filling spheres
 may even be shadowed. The molecule may be manipulated using scroll bars,
 the interactive command line or from a dials box if attached. The resulting
 image may be saved at any point in PostScript, GIF, PPM, Sun rasterfile or
 Microsoft BMP formats.  For more details see the RasMol user reference.
 It was claimed at a recent conference to be the fastest available
 uniprocessor program for drawing shadowed spacefilled molecules. On a
 SparcStation it can shadow a 10,000 atom protein in less than 10 seconds.
     The current version of the program has been tested on sun3, sun4, sun386i,
 hp9000, sequent, DEC alpha, IBM RS/6000 and SGI, DEC and E&S mips based
 machines compiled under both gcc and the native compiler. The version for
 Microsoft Windows requires version 7 of the Microsoft Optimizing C Compiler
 and the Microsoft Software Development Kit (SDK).
     The source code is public domain and freely distributable provided that
 the original author is suitably acknowledged. Any comments, suggestions or
 questions about the package may be directed to "rasmol -8 at 8-
