|New Features||Enhanced Functions|
|◆||The new POV-Ray interface lets you prepare photorealistic graphics containing sky spheres, multip lelight sources, textures and shadows.||◆||Structures with no cell and symmetry given are
now supported directly. These can be converted into crystal structures and vice versa.
|◆||Best or hkl planes and lines are available for both display and evaluation of geometric information like distances or angles between planes, lines and points.||◆||Additional molecular file formats and an optional data import assistant to confirm the (automatically detected) file format.|
|◆||Vectors can be assigned to atoms e.g. to indicate a magnetic moment.||◆||The models ball-and-stick, wire, space-filling, and ellipsoid can now be assigned to individual atoms or groups of atoms rather than defined globally, which allows to mix different models within one structure picture.|
|◆||Video sequences can be recorded to create e.g. AVI files.|
|◆||An optional assistant helps you to create a (new) structure picture. A variant of this assistant, the Auto-Builder, can create pictures automatically or according to a user-defined strategy. This is helpful when you frequently change the structural parameters or browse through data sets from crystal structure databases.||◆||ORTEP-like styles, such as open octants, are not more limited to flat mode but also available in rendering mode.|
|◆||Improved layout mode for printout pages, new layout format for fixed-sized bitmaps. Improved automatic adjustment and placement of objects in the window or on the page, rsp.|
|◆||A Diamond 3 document may contain multiple structural parameter sets and multiple pictures for every structure in a document. You can copy or shift structures or pictures between different documents.
(Diamond 2 format is of course automatically supported during opening or saving of DSF files.)
|◆||Distances and angles table now provide histograms and statistics.|
|◆||The Object Info window has been enhanced to a new Property window and shows information in
context with the current situation, e.g. properties of the selected atom, distances and angles between the selected atoms, and many more.
|◆||Pictures associated to a structure or all pictures of a document can now be surveyed in thumbnail view.||◆||Walk-through mode and several more enhancements
for movements. New spin option to accelerate motion in tracking mode.

ENDEAVOUR is a powerful software for crystal structure solution, both from powder as well as single crystal diffraction data. Based on more than ten years of experience, the software is capable of solving many small to medium sized structures more or less on its own. The innovative concept combined with the elaborate user interface makes solution of crystal structures an almost routine process, especially for inorganic but also for many organic compounds. Even unexperienced users can prepare and perform the structure solution calculation in a few steps:
Simply follow the integrated "wizard" to enter the required data (unit cell parameters, chemical composition, diffraction data), and let Endeavour do the rest. The structure solution is performed using a special variant of the "direct-space" approach, namely a combined global optimization of the difference between calculated and observed diffraction data and of the potential energy of the system. Due to the additional usage of the potential energy, the method is much less sensitive to low-quality diffraction data than e.g. direct methods.
- Structure solution from X-ray laboratory, synchroton, neutron or electron diffraction data
- Required input: unit cell parameters, chemical composition / molecule structure, diffraction data
- Powder diffraction data (integrated intensities at Bragg angles 2theta) or single crystal diffraction data (I(hkl), |F(hkl)| or F2(hkl)) can be used
- "Wizard" for the easy preparation of the input data
- Automatic adjustment of calculation parameters
- Automatic space group determination from resulting structure
- Viewing of the intermediate steps of the structure solution process: structure picture, progress (%finished), R-Factor, etc.
- Support for structures with single atoms on special positions as well as for molecular structures (incl. rotatable bonds)
- Automatic variation of special positions for single atoms during structure solution calculations in space groups higher than P1
- Structure solution/prediction either by energy minimization or from diffraction data alone is possible

Match! is an easy-to-use software for phase identification from powder diffraction data. It compares the diffraction pattern of your sample to a database containing reference patterns, in order to identify the phases that are present. Additional knowledge about the sample like known phases, elements or density can be applied easily. In addition to this qualitative analysis, a quantitative analysis (using Rietveld refinement) can be performed as well.
As reference database, you can apply the included free-of-charge COD database and/or any ICDD PDF product, use your valid ICSD/Retrieve (-2002) license, and/or create a user database based on your own diffraction patterns or crystal structure data. You can easily setup and run Rietveld refinements from within Match!, with the actual calculations being performed automatically, using the well-known program FullProf (by J. Rodriguez-Carvajal) in the background. Match! provides a gentle introduction into Rietveld refinement, from fully automati operation to the “Expert” mode.
Another major improvement is the ability to display multiple experimental patterns on top of each other. Match! runs on Windows, Mac OS X and Linux.
