I'll add my 2 calories then. Gerard's new naming carefully avoids the "Factor" and "Amplitude". The following term should get everybody to agree: "FA-free STRUDL".
Example of politically correct use: "It is good practice to deposit your FA-free STRUDL in the Protein Data Bank along with the atomic coordinates" Thierry -----Original Message----- From: CCP4 bulletin board [mailto:ccp...@jiscmail.ac.uk] On Behalf Of Gerard Bricogne Sent: Monday, January 12, 2009 02:34 PM To: CCP4BB@JISCMAIL.AC.UK Subject: Re: [ccp4bb] structure (factor) amplitude Dear Gerard, As usual, your contribution is a hard act to follow. However, given that your actual proposal can be rather indigestible (especially with lots of cream) we might have to stick with the current options. What the perusal of James has revealed is that, if we want to respect the terminology that Ewald and he introduced, "structure amplitude" and "structure factor amplitude" cannot be considered as synonyms - which finally answers Bernhard's question, Google results notwithstanding. With best wishes Gerard. -- On Mon, Jan 12, 2009 at 08:21:40PM +0100, Gerard DVD Kleywegt wrote: > As suggested by Tassos, what we need now more than ever is some Dutch > diplomacy so that he healing can really begin.
