MOLecule analysis and MOLecule display

Release 2K.2 of MOLMOL available!
MOLMOL is a molecular graphics program for displaying, analyzing, and
manipulating the three-dimensional structure of biological macromolecules,
with special emphasis on the study of protein or DNA structures determined
by NMR. The program runs on UNIX and Windows NT/95/98/2000 and is freely
A more detailed introduction is given on the page
originally created for the BRUKER web
site. There also is a (very dated)
official project description.
If you want to know more, it is best to look at the
hypertext version of the manual.
This also contains a full list of features. We also have a
tutorial showing a few step by step
examples, and the online manual
pages are available in hypertext format. All these files are also
distributed with the program.
The program was written by Reto Koradi
(see also his picture) under the supervision of
Martin Billeter, in the group
of Prof. Kurt Wüthrich.
Our whole group contributed a lot
with testing and many helpful suggestions.
We have a gallery of nice images created
with MOLMOL by ourselves, and another one with
images by outside users.
We also have a MOVIE (not of very high artistic
or scientific value, more a feasibility study).
The program is freely available for everybody. Please note that
this does not mean that it is public domain in
the true sense. A file giving the detailed conditions accompanies the
program and can also be read directly here.
As long as you just use the program, and do not plan to copy, modify
or redistribute it in any way, there is just one simple rule:
Whenever figures prepared by MOLMOL are used somewhere, like in
publications or lectures, you must include a reference
to the following paper, normally in the figure caption, something like
"figure prepared with the program MOLMOL (Koradi et al., 1996)":
