Abstract
The Daresbury Laboratory Laue Software Suite is a set of programs developed
for the processing of Laue X-ray diffraction data. The Laue method using
polychromatic radiation poses a number of problems which are not present
in data collected using monochromatic methods. These include the requirement
to determine a wavelength normalisation curve, the presence of spots which
are exactly superposed multiple reflections (harmonics), the occurrence
of spatially overlapping spots (especially for large unit cells) and
the wavelength dependence of film to film scaling factors where film
packs are used. The original suite was designed to be run on standard
terminals supporting T4010 graphics. More recently, X-windows based code
has been developed for the initial stages of the data processing. The
programs in the suite carry out the processing stages required from
scanned images to a merged set of integrated intensities. An
overview of the suite indicates
the main processing stages and the programs used.
Programs Available
The suite comprises the following programs:-
Utilities:
Laue Specific Libraries:
A set of programs for handling gnomonic
projections is also available.
Documentation
There is an Overview Document available and
also a separate Processing Flow Chart to
act as starting points for investigating the suite.
Each program (see above) has its own documentation.
News and Updates
An updates file gives details of all
recent updates made to the Laue suite and also some recent items of
news concerning the suite.
Test Data
Sets of test data are also available with the suite. Some
standard tests are provided to check out the
programs and to assist the user in learning how to use the programs.
Availability
The program suite is installed on the Protein Crystallography Village
computer 'dlpx1'. The suite is maintained and distributed from the
Daresbury Laboratory and is currently licenced free to academic users
See the Laue suite installation notes for
for details on the conditions of distribution and how to obtain a copy of
the suite.
Contact
Following John Campbell's retirement, Quan Hao
(qh22@cornell.edu) has agreed to take
responsibility for the suite.
