(Apologies as XND should have been auto-mirrored on the CCP14 sites around the 17th Jan but it looks like some routers near Grenoble may be taking a disliking to TCP-IP packets originating from the ccp14.ac.uk domain(?)) The latest XND 1.20 Rietveld for UNIX and PC by Jean-Francois Berar is now available with source code from the home site and CCP14 UK mirror. ftp://old-labs.polycnrs-gre.fr/pub/xnd/xnd_1.20.tar.gz http://www.ccp14.ac.uk/ccp/ccp14/ftp-mirror/xnd/pub/xnd/xnd_1.20.tar.gz ---- Some features include: Source of the program is written in ANSI C language Normal and incommensurate structures Refinement of multiple high temperature diffraction patterns Joint refinement of X-ray and Neutron (const wavelength) powder data No soft limit to the number of phases Can handle parasitic lines (Cu K beta, Tungsten, etc) Pattern Matching/Le Bail extraction Treatment of profile asymmetry Rigid body constraints and penalties on bond lengths. Preferred orientation functions defined in the reciprocal lattice The latest manual is inside the distribution file in HTML format. For PC-DOS/Windows users, if you have trouble getting WinZIP and other programs to extract the files, refer: http://www.ccp14.ac.uk/tutorial/xnd/install_windows.html (WinZIP and other programs need the downloaded filename in the format .tar.gz or .tar.Z to handle things correctly) ---- (CCP14 mirrors in Australia and Canada should be updated in a day or so) Lachlan. -- Lachlan M.
