Crystallography web watch

The ACA Communications Committee continues its 'Web Watch' in an attempt to keep members informed of useful websites, primarily of the crystallographic persuasion.

Collaborative Computational Projects (CCPs) — The goals of these British-funded projects are to develop, maintain and distribute computer programs and to promote the best research computational methods in biology, chemistry, physics and engineering. Sites of particular interest to crystallographers: CCP4 (protein crystallography): www.ccp4.ac.uk/main.html, CCP13 (fiber, polymer diffraction): www.ccp13.ac.uk/ and CCP14 (powder, small molecule single crystal diffraction): www.ccp14.ac.uk/index.html.

Linux for Crystallography — The number of crystallographic programs that run under the Linux operating system is rapidly expanding. Look for programs currently available at zeus.polsl.gliwice.pl/~nikodem/linux4chemistry.html, www.ccp4.ac.uk/newsletter36/11_linux.html, or, www.fos.su.se/struc/linux/linuxtal.html.

Crystallographic Software — Network Science has a site that lists crystallographic software from A-Z: www.netsci.org/Resources/ Software/Struct/xray.html.

ChemSoc — The Royal Soc. of Chemistry’s chemical science network contains considerable information, including a visualinterpretation of the periodic table, a timeline of events in chemical history, access to conference and society information, IUPAC draft recommendations, career information, and a listing of web links to a variety of databases: www.chemsoc.org.

Macromolecular Crystallization — Two nice websites are T. Bergfors’ Pictorial library of crystallization drop phenomena: xray.bmc.uu.se/~terese/crystallization/library.html and J. Zeelen’s X-tal protocols: www.mpibp-frankfurt.mpg.de/~johan.zeelen//xtal.html.
