- RasMol is a molecular graphics program intended for the visualisation
- of proteins, nucleic acids and small molecules. The program is aimed at
- display, teaching and generation of publication quality images. The program
- has been developed at the University of Edinburgh's Biocomputing Research
- Unit and the Biomolecular Structures Group at Glaxo Research and Development,
- Greenford, UK.
-
- RasMol reads in molecular co-ordinate files in a number of formats and
- interactively displays the molecule on the screen in a variety of colour
- schemes and representations. Currently supported input file formats include
- Brookhaven Protein Databank (PDB), Tripos' Alchemy and Sybyl Mol2 formats,
- Molecular Design Limited's (MDL) Mol file format, Minnesota Supercomputer
- Center's (MSC) XMol XYZ format and CHARMm format files. If connectivity
- information and/or secondary structure information is not contained in the
- file this is calculated automatically. The loaded molecule may be shown as
- wireframe, cylinder (drieding) stick bonds, alpha-carbon trace, spacefilling
- (CPK) spheres, macromolecular ribbons (either smooth shaded solid ribbons
- or parallel strands), hydrogen bonding and dot surface. Atoms may also be
- labelled with arbitrary text strings. Different parts of the molecule may be
- displayed and coloured independently of the rest of the molecule or shown in
- different representations simultaneously. The space filling spheres can even
- be shadowed. The displayed molecule may be rotated, translated, zoomed,
- z-clipped (slabbed) interactively using either the mouse, the scroll bars,
- the command line or an attached dials box. RasMol can read a prepared list
- of commands from a `script' file (or via interprocess communication) to
- allow a given image or viewpoint to be restored quickly. RasMol can also
- create a script file containing the commands required to regenerate the
- current image. Finally the rendered image may be written out in a variety
- of formats including both raster and vector PostScript, GIF, PPM, BMP, PICT,
- Sun rasterfile or as a MolScript input script or Kinemage.
-
- RasMol will run on a wide range of architectures and systems including
- SGI, sun4, sun3, sun386i, SGI, DEC, HP and E&S workstations, IBM RS/6000,
- Cray, Sequent, DEC Alpha (OSF/1, OpenVMS and Windows NT), IBM PC (under
- Microsoft Windows, Windows NT, OS/2, Linux, BSD386 and *BSD), Apple
- Machintosh (System 7.0 or later), PowerMac and VAX VMS (under DEC Windows).
- UNIX and VMS versions require an 8bit, 24bit or 32bit X Windows frame
- buffer (X11R4 or later). The X Windows version of RasMol provides optional
- support for a hardware dials box and accelerated shared memory rendering
- (via the XInput and MIT-SHM extensions) if available.

- The source code is public domain and freely distributable provided that
- the original author is suitably acknowledged. The complete source code and
- user documentation may be obtained by anonymous FTP from ftp.dcs.ed.ac.uk
- [129.215.160.5] in the directory /pub/rasmol. The source code, documentation
- and Microsoft Windows executables are stored in several files appropriate
- for the receiving operating system. Please read the "README" file in the
- distribution directory. UNIX and VAX systems should retreive either
- RasMol2.tar.Z, RasMol2.tar.gz. Apple Mac users should retrieve RasMac.sit.hqx.
- Microsoft Windows users should retrieve RasWin.zip and optionally the Visual
- Basic package RasMenu.zip. All these files include source code, on-line help,
- user manual and reference card. RasMac.sit.hqx, RasWin.zip and RasMenu.zip
- also contain executables for the required platform. Please remember to use
- "binary" mode when transferring these files between systems. Check that the
- file size is the same before and after transfer.
-
- Any comments, suggestions or questions about the package may be directed
- to the author at "rasmol@ggr.co.uk".
