2007-05-30 Thread Jacob Keller
Dear Crystallographers, I have been wondering recently whether the anomalous component of a diffraction pattern is of a different wavelength from the regular diffraction pattern. It seems reasonable as resonant scattering seems to be akin to fluorescence, although as I understand it, is not exa

Hello Ibrahim, from the name of the library I would guess it belongs to the IBM compiler. Since you probably don't want to install it only to run Delphi (because it costs quite a bit), you would have to contact the authors of Delphi to recompile their program. Many compilers come with a switc

There are several scenarios and it is hard to generalise. Certainties are: 1) The better your data the easier it is to see a ligand. At 3A it can be hard to model a blob, but it is usually straightforward at 2A. It is harder if your data is twinned etc.. 2) There is a lot of unnecessary and co
