Based on the demonstrations given by Rene de Gelder at the IUCr Glasgow software Fayre, there is a minor tutorial run-through of the CRUNCH direct methods structure solution software (R. de Gelder and R.A.G. de Graaff) at: http://www.ccp14.ac.uk/tutorial/crunch/install.html CRUNCH has a reputation for solving difficult structures and is the program that solved on the C28H37O6N structure problem posted by John Huffman on the sci.techniques.xtallography newsgroup in April 1994. CRUNCH is quite trivial to install and run under UNIX (including the freely available LINUX Operating System) It is available from the following pages: HOME WEBSITE: http://www-xtal.sci.kun.nl/xtal/documents/software/crunch.html CCP14 Mirrors: http://www.ccp14.ac.uk/ccp/web-mirrors/dirdif/xtal/documents/software/crunch.html ftp://ftp.minerals.csiro.au/pub/xtallography/ccp14/ccp/web-mirrors/dirdif/xtal/documents/software/crunch.html http://ccp14.sims.nrc.ca/ccp/web-mirrors/dirdif/xtal/documents/software/crunch.html DOWNLOAD VIA: http://chemb0b.leidenuniv.nl:80/~rag/ CCP14 Mirrors: http://www.ccp14.ac.uk/ccp/ccp14/ftp-mirror/dirdif/~rag/ ftp://ftp.minerals.csiro.au/pub/xtallography/ccp14/ccp/ccp14/ftp-mirror/dirdif/~rag/index.html http://ccp14.sims.nrc.ca/ccp/ccp14/ftp-mirror/dirdif/~rag/index.html ========= For those only running Windows on their PCs, there is a page on how to create a dual boot Windows/LINUX system at the CCP14 site.
