Dear Jacob, there was a nice small computation project by Anne Bochow published in the CCP4 Newsletters (2005),
http://www.ccp4.ac.uk/newsletters/newsletter42/content.html , communication 9, illustrating how strong and how confusing the ripples may be indeed; if you want I may send it you off list the corresponding pdf file. Please make a look the figures, they are very impressive. And Pavel just commented how to distinguish such the ripples from the peaks for the deformation bond density. With best regards, Sacha Urzhumtsev ________________________________________ De : CCP4 bulletin board [CCP4BB@JISCMAIL.AC.UK] de la part de Keller, Jacob [kell...@janelia.hhmi.org] Envoyé : jeudi 5 février 2015 21:53 À : CCP4BB@JISCMAIL.AC.UK Objet : Re: [ccp4bb] proton scattering by X-rays What about the bogey of Fourier truncation ripples--I have heard many have been fooled by the into thinking they were seeing orbitals. How does one tell the difference? JPK
