The LMGP suite for Windows by Jean Laugier and Bernard Bochu contains a number of programs useful for crystallography, Laue Diffraction and Powder Diffraction. OrientExpress - "The program OrientExpress makes it possible to orient a single crystal of known unit cell dimensions from a single Laue pattern. This pattern can be registered on a flat or cylindrical detector : X Rays film, two-dimentional sensitive detector, bitmap picture. The program was succesfully applied to X rays (normal wavelength and hard X rays) and neutrons experiments, as well as to every sort (mineral, organic and protein) of crystals." Equiv - given a spacegroup: equivalent positions, extinctions/systematic absences, equivalent reflections are listed. Individual HKLs and atomic coordinates can be inserted to obtain this out put. indx - given an input of the cell, spacegroup and wavelength, this program for calculates powder diffraction line positions, HKLs and multiplicities; as well as provide extinctions/systematic absence conditions. celref - unit cell refinement and HKL calculation; overlaying the results on the raw data. Poudrix - Powder Pattern Calculation of Synchrotron/Laboratory X-ray and Neutron Powder Diffraction Patterns including the ability to use Anomyaous Dispersion co-effecients at all wavelengths. Poudrix also comes with the DISPANO program "Anomalous Scattering factor display software" which can display data according to "Brennan and Cowan" or Sasaki" Wulff - Wulff Map generating software. DISPANO - "Anomalous Scattering factor display software" which can display data according to "Brennan and Cowan" or Sasaki" Obtaining and installing the LMGP suite Just get the zip files for the programs you wish to use at (http://www.ccp14.ac.uk/ccp/web-mirrors/lmgp-laugier-bochu/) and extract into any subdirectory on C-drive that takes your fancy. It is best to run the programs at not less than 1024x768 screen resolution. Though some of the programs can run at less than this.
