The Computational Crystallography Toolbox (cctbx) is being developed as the open source component of the PHENIX system. The goal of the PHENIX project is to advance automation of macromolecular structure determination. PHENIX depends on the cctbx, but not vice versa. This hierarchical approach enforces a clean design as a reusable library. The cctbx is therefore also useful for small-molecule crystallography and even general scientific applications.
To maximize reusability and, maybe even more importantly, to give individual developers a notion of privacy, the cctbx is organized as a set of smaller modules. This is very much like a village (the cctbx project) with individual houses (modules) for each family (groups of developers, of any size including one).
The cctbx code base is available without restrictions and free of charge to all interested developers, both academic and commercial. The entire community is invited to actively participate in the development of the code base. A sophisticated technical infrastructure that enables community based software development is provided by SourceForge. This service is also free of charge and open to the entire world.
The cctbx is designed with an open and flexible architecture to promote extendability and easy incorporation into other software environments. The package is organized as a set of ISO C++ classes with Python bindings. This organization combines the computational efficiency of a strongly typed compiled language with the convenience and flexibility of a dynamically typed scripting language in a strikingly uniform and very maintainable way.

I will write something proper soon...........
Our research group is interested in methodological improvements and practical aspects of X-ray structure determination and analysis, and in particular in the electron density distribution of solids. Our focus and area of expertise is the inclusion of the non-spherical electron density in structural models of "small-molecule" (up to 1000 atoms) crystal structures. However, it is the discipline of chemistry that provides us with a broader framework of phenomena and questions. One theme uniting the different branches of chemistry, ---organic, biological, medicinal and inorganic--- is structure. X-ray structure analysis is also a playground for the application of computational chemistry, in that it provides real-life examples for study, comparison and verification. Only the mutual exchange of information between experiment and theory enables to distinguish between manifestations of thermal motion and electron density in the solid state. Therefore our studies require the application of advanced computational methodology. Modern computer programs based on quantum mechanics and molecular mechanics are central tools that we use, methods that are complemented by preparational chemistry and crystallisation in the laboratory. Last but not least it is the diffraction experiment itself that X-ray structure analysis is based upon. In order to "measure" the electron density and to derive molecular strucure of a compound of interest each time such an experiment needs to be carried out. Obtaining chemical insight and attempting to arrive at a deeper understanding of the phenomena observed in such experiments is the ultimate motivation for our studies. For more detailed information the reader is refered to our publication list. The work listed there has often involved collaboration partners, and some them are refered to here.

This collection contains source code for crystallographic programs that are either no longer actively maintained or have a version archived at a significant point in its historical development. Note that many of them (especially ones with graphic output) will not work without considerable modification to fit the requirements of modern compilers and libraries.
The museum was first created by Armel Le Bail in 1999 (http://sdpd.univ-lemans.fr/museum/
), where it was subsequently found a useful resource by a number of software developers wishing to peruse old code and ideas. It was transferred to the IUCr Computing Commission website in January 2010 by Lachlan Cranswick.
Crystallographic source code of any type, style and age (as a zip file) can be submitted for inclusion into the museum by contacting the Chair of the Computing Commission (who is currently: Harry Powell)

X-ray Absorption Edges
A periodic table allowing you to select an element and see the X-ray absorption edge energies in angstrom (wavelength). It also provides access to the scattering factors for each element. These data files indexed through the table were calculated using the subroutine library by Brennan and Cowan. The values for f' and f" are derived using the theoretical approximation developed by Cromer and Liberman. This theory gives accurate values far from an absorption edge but does not account for the effects of neighboring atoms, which can be very substantial near an absorption edge. Before conducting an anomalous scattering experiment close to an absorption edge it is therefore advisable to determine the actual scattering behaviour of your sample.

A web resource for structures with Z' > 1
Structures with Z' > 1 (i.e. more than one molecule in the asymmetric unit) are of intense current interest. As part of an EPSRC funded project, a web site has been developed dedicated to bringing together all the information and publications known about these fascinating systems.
The main feature of the website is an annotated database of structures with Z' > 4, which is updated regularly. Each entry contains the name, chemical formula, journal reference and Cambridge Structural Database (CSD) Refcode (where applicable) in addition to a "Notes" section reporting anything of interest about the packing or composition of the asymmetric unit, as well as links to polymorphs, redeterminations or similar structures. Possible errors in Z' or space group assignment are also highlighted. The structures included in the database are mainly drawn from the CSD however readers with unpublished high Z' structures are also invited to submit their structures for inclusion in the database.
The website also contains a general introduction to the Z' phenomenon as well as a list of useful references concerning all aspects of high Z' structures.
