This program was developped in collaboration with Radovan Cerny, and was written at the Laboratory of Crystallography, in Geneva (Switzerland), with support from the Swiss National Science Foundation. (project #21-53847.98)). The development still goes on as a personal research project after my move to the ESRF.

See the ObjCryst++ homepage for more details about the source code.

NEWS

Latest version is 1.1 (january 8th, 2002). It features speed improvements, use of integrated R(w)-factors (for a better handling of patterns with badly defined profiles), the possibility to use single crystal data (eg extracted intensities), overall temperature factor, a better handling of molecules (importing zmatrices and therefore pdb), and is more user-friendly (eg no need to hit 'return' after each input). See the full changelog.
Introduction
The FOX program was made for the structure solution from powder diffraction data. Its most interesting features for ab initio structure determination are : So, if you have: Then FOX can help you.

This program can be used also for educational purposes , to show a 3D display of Crystal structures, and the associated powder pattern(s) (see how adding atoms, changing the lattice, or changing the spacegroup affects the powder spectrum and the 3D structure).

If you would also like to choose your own criterion and algorithm to solve the structure, then it will be even better : FOX is built on a very customizable and expandable library, which allows you to evaluate your Crystal structure following a combination of criteria: currently there are only R, Rw factors and an Anti-bump cost function, but it would be very easy to write a new criterion using (say) interatomic distances (energy of the configuration, analysis of the coordination). This is what makes this program different from other available programs.

For example currently you can combine several Powder patterns (X-Ray, Neutron,...) for the same structure,...

Download
FOX is available in precompiled form for Windows (tested on 98, NT SP4) and Linux-x86 (the source code is available along the ObjCryst++ code-see the ObjCryst++ home page for info). You can download from several sites: For Windows, download the Fox-20020108.zip file.

For Linux, download the Fox-20020108.tar.bz2.

Installation
If you have problems with the linux install send me an email.
