Here's a list of additions/changes to this site since Feb. 10, 1996,
most recent first. For visiting and downloading rates at this site, see
Site Statistics. In 1999, this site was visited
by 6,000 people/week during the academic year, and 4,000 people/week
during the summer.
08/07/12: This site, formerly titled the RasMol Home Page,
was renamed the RasMol Classic Site, in deference
to the current RasMol Home Page,
Jmol-based resources were recommended as an alternative to RasMol, and
Chime-based resources were deprecated.
00/08/28: In a major transition, emphasis of the
on this site changed from RasMol to Protein Explorer.
00/08/10: An update was provided
for participants in the 1997-1999 NSF-funded Workshops on
Molecular Visualization in Biological Science Teaching.
PDB Lite page was updated to ensure that all mirrors linked here
keep their databases up with weekly updates of the Protein Data Bank,
and that all sites are working properly.
00/06/26: The section listing the van der Waals radii used
by Chime and RasMol for spacefilling and dots has been revised and expanded in the
FAQ. It now includes the "united atom"
radii previously disclosed only in the email list discussion (and still
not mentioned under 'spacefill' in the reference manual).
99/08/20: The FAQ now includes
Where can I find out how to use the "select" command?
What are the values used by RasMol and Chime for van der Waals radii in the spacefill rendering?
99/08/17: I have provided a new document for the FAQ,
which addresses these questions:
99/07/28: Two websites of major importance have recently moved.
All resulting broken links to
ExPASy have been fixed, and the most important 26 links to
the former Brookhaven PDB have now been fixed to work with the
new PDB at RCSB. (There are still
about 20 rarely used links to BNL not yet fixed.)
99/06/29: Thanks to the efforts of Herbert Bernstein,
Roger Sayle, Arne Mueller, and others, RasMol lives! In April,
RasMol 2.7 with several important new
capabilities. (It was announced on the RasMol
99/03/13: Thanks to Eric Francoeur, I have corrected my
spelling of Koltun in every place I could find it. Koltun is
the K in CPK. In case you have a local copy of
cpk.gif found in the reference manual and elsewhere on this site,
you may wish to download the corrected
99/02/11: Can RasMol be distributed freely, on CD-ROMs, and
used freely even for commercial purposes? Roger Sayle's resounding
has been included in
his section of the FAQ.
98/12/07: Is RasMol year-2000 (Y2K) compliant? Roger Sayle's
definitive answer has been added to his section of the
98/06/22: At long last, a
Guestbook has been created! You can now add links to your favorite resources
to the RasMol Classic Main Page.
(The Guestbook was discontinued ca. 2000 because it was superceded by
The Guestbook is linked to the Index Page
and has several sections devoted to specific topics. These topical
sections are in turn linked to relevant pages at this site.
We regret that maintenance of this site
has overtaxed the resources which we have to devote to it, and scores
of suggested links have not been completed. Hopefully, this Guestbook
will help to alleviate this problem.
98/06/22: Under Other Software, links
have been added for Kurt Wüthrich's MolMol which, together with
Pov-Ray, produces beautiful publication-quality images.
98/06/07: There is a new search interface at the Brookhaven
Protein Data Bank called PDB Lite.
PDB Lite was designed by Eric Martz and
implemented by Jaime Prilusky at the invitation of the Director of the
Protein Data Bank, Joel Sussman. PDB Lite makes it easier for students
and educators to find, view, and download PDB files for
macromolecules. The original search interface, the 3DB Browser
created by Jaime Prilusky, remains available to provide
the power and flexibility needed
by crystallographers and protein structure specialists, but is rather
technical and complex for novices or occasional users.
PDB Lite is linked to our page for
98/05/16: PDB files for thousands of pharmaceuticals are available
from the Akira Dobashi group's site at Tokyo University in Japan.
Links are under Micromolecules
and the World Index of Animated Tutorials in Chime;
each molecule is also shown in Chime with molecular dynamics animation!
98/04/27: A new guide to Select Commands in
Chime and RasMol has been provided. It explains how to select or
restrict (hide) atoms, residues, chains, ligands, groups of residues
(such as hydrophobic or charged), and nearest neighbors. It is linked
to RasMol Tutorials, and to several other
98/04/13: For our workshops, a quick
reference handout has been prepared listing the RasMol/Chime Color RGB Values in decimal and
hexadecimal. This is helpful when making an HTML color key for Chime's
98/04/02: What can you learn about
a protein/DNA molecule with RasMol? has been revised and expanded.
It now includes not only a section which specifically
examines the protein:DNA complex 1d66.pdb, but also a new generic section
designed to guide you through the exploration of any macromolecule of
98/02/28: More detailed information about RasMol's slab
command has been added to the
98/02/27: College faculty in the New York City area (USA): there
is less than a week remaining to register for the
workshops at LIU, Brooklyn. Only a handful
of slots remain open.
98/02/26: The starter package of molecules offered to beginners
has been made more exciting. The ATP now has double bonds, and in
addition to the traditional protein:DNA complex (1d66.pdb), oxygenated
human hemoglobin and a lipid bilayer containing a channel have been
added. Get these from RasMol Quick Start.
98/02/24: Further improvements have been made to the page Where does one get "molecules", including the
repair of the broken links, thanks to Aron Sacchetti.
98/01/01: Swiss-PDBViewer can save subsets of residues in an
existing PDB file, and optionally with rotation, translation, and center
specified by the user. Details kindly provided by Nicolas Guex are at
97/12/26: Information has been compiled on the capabilities
of RasMol, Chime, and WebLab to save subsets of atoms and modify
existing PDB files. See PDB Tools,
also linked under the Martz FAQ and under
97/11/16: Visiting statistics have been analyzed for the past
academic year. Nearly 2 million files were served to 90,000 people
from 90 countries! See Stats.
97/11/11: The image of heme at the top of our
Gallery has been provided in an alternate form with a white background
suitable for printing.
97/11/04: Dates have been set for the 1998 series of free, NSF-supported
workshops taught by Eric Martz in Amherst MA and New York City. These
enable college faculty to use molecular visualization in their teaching.
(Participants pay their own travel.)
97/08/06: A new Overview of molecular
visualization resources for teachers is available. This was
designed for a one-page flier to hand out at the International Union of
Biochemistry and Molecular Biology in San Francisco, August 24-29, and
at the Education Satellite Meeting the preceding weekend.
97/07/29: Provided a new first page with
an animated GIF to show rotation to those
who have never seen it, and have not installed RasMol nor Chime. A new
and better search interface has been
provided for searching this site. Thanks to Chris Finlayson for his
design and implementation of the new first page and search interface.
97/04/01: A list of frequently asked questions, with answers,
has been contributed by Roger Sayle. My apologies to Roger for
taking far too long to find the time to put this
very useful FAQ on the web site.
97/04/01: Babel, a web interface to Babel, MolView, and other links were
added to the page on free software other than
RasMol, which was also reorganized and better indexed. Now included
is an amazing web form which allows you to submit a PDB to RasMol and
get back a single image without ever running RasMol! See the
Molecule to Image Converter Engine.
97/04/01: The broken downloading link for
Win32SOle has been fixed.

studying the methods used, or using as templates from which to build new
96/11/20: Roger Sayle has kindly provided a new version of RasWin
for Windows computers without floating point hardware (e.g. 386SX). He
has also fixed some bugs in the 16- and 32-bit versions which require

versions have been added installation instructions for Windows 95.
Also, the PDB downloading instructions have been
updated to reflect
Brookhaven's newer 3DB Browser pages, their application/x-rasmol

roadblock encountered by first-time RasMol script runners". Updated
visiting rate statistics page.
