The LMGP suite for Windows by Jean Laugier and Bernard Bochu contains a number of programs useful for crystallography, Laue Diffraction and Powder Diffraction. LMGP Suite homepage at : http://www.ccp14.ac.uk/tutorial/lmgp/ 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. Gretep - Structure plotting software including ability to handle thermal ellipsoids. Will plot structures, can do custom labels and retain this information in the saved file. Mean Plane calculations and much more. 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. chekcell - graphical powder indexing helper tool that links into the Crysfire Powder Indexing suite by Robin Shirley. http://www.ccp14.ac.uk/tutorial/crys/ chekcell can also handle Celref cry files and manually inputted cells. truecell - From a given cell, this program seaches more symetric multiple cells. This can be useful where powder indexing programs favour small cell low symmetry cells - where a truer cell might be a higher volume higher symmetry cell. Truecell is also inplemented inside Chekcell. http://www.ccp14.ac.uk/tutorial/crys/ truecell can also handle Celref cry files and manually inputted cells. LePage for Windows: - windows port of LePage using the fortan code of Ton Spek and A. Meetsma. LePage determines the metrical symmetry of a given lattice including sub cell and super cell searching. LePage is also implemented inside the latest version of Chekcell. LePage is already included in single crystal suites such as WinGX and Platon. But LePage for Windows can be useful as a stand alone program, especially for powder diffraction based problems. 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" Scatfac - "Scattering Factor display software" which cal also export ASCII or EXCEL friendly data." wgetspec - Windows port of U.D.Altermatt and I.D.Brown's spacegroup software Getspgr - converting Symmetry Operators into a Spacegroup Symbol / Spacegroup Number (If you wish to cut and paste in Shelx spacegroup operators use "File, Keyboard positions aquisition") 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.
