Re: [ccp4bb] looking for a link between diffraction resolution and order within the crystal

Thank you everyone for your contributions that help me understand more. Let me try to rephrase my initial post: Say that I have diffraction up to 6A resolution, I would say that my crystal is decently ordered (see the glass half full), enough for observing repeating units that do not fluctuate

Dear Vincent, The resolution limit of reflections is a consequence of the closest distances in the structure that are consistent repeating units in the crystal lattice. This is not automatically linked to any particular features of a structure per se. In addition, while some of the structural fi

Hi Alexandre, I was curious if I could also get a copy of the illustrations if it wont be too much trouble? I was more curious about 0.0 - 4.0 Ang region if that saves you some effort. Thank you for this. Matthew Merski On Tue, Nov 28, 2017 at 4:12 PM, Alexandre Ourjoumtsev < alexander.ourjoum

Dear Vincent, first, certainly, you can continue to a higher resolutions distinguishing further details : 3.3 A - nucleic acid pairs 1.2 A - atomic details 0.9 A - deformation density (by the way, there was a relevant work, I think, by E.Blanc and G.Bricogne beginning of 2000, about

Hi, I've been searching but can't find what I am looking for so I thought I ask specialists. I am curious about the link between resolution limits of reflections on the detector, and what features are ordered in real space. I saw the great movie by James Holton on resolution and features in t
