[ccp4bb] Postdoctoral position in Microbial Glycobiology

Dear all, We have an opening for a postdoctoral researcher with a strong interest in microbial secretion systems, complex carbohydrates, and structural biology. The project involves functional reconstitution of glycosyltransferases and associated components implicated in microbial cellulose bi

Re: [ccp4bb] "Atomic resolution"

Dear Jacob, >Also, resolution would depend a lot on phase accuracy/precision, no? I feel that there is a traditional confusing between the terms, which "resolution" you are talking about since this term is over-used: - resolution of a particular map (then it may be local or a kind of an over

Re: [ccp4bb] "Atomic resolution"

Good topic, I just had a related thought: can I use the term in my NMR course to say it's the only spectroscopy that gives atomic resolution - meaning, here, that every NMR-active atom is distinguishable from its neighbours thanks to its unique chemical shift. At good enough resolution, i.e

Re: [ccp4bb] "Atomic resolution"

Hi Jacob If there’s fresh air between atoms in coot and you can assign the element by eye it’s atomic resolution to me Probably corresponds to about 1.2A or thereabouts I do however also respect the 0.8A limit used by our chemical crystallography colleagues My two cents... Best wishes Graeme

Re: [ccp4bb] "Atomic resolution"

My answer is not precise, I just try to give students something they can remember, so they don't go and model water for example at an inappropriate resolution. Of course phasing matters as well. On Thu, Jan 11, 2018 at 2:31 PM, Keller, Jacob wrote: >>I tell people it is when your resolution is l

>I tell people it is when your resolution is less than the bond length that >connects the two atoms. I thought this was sort of a pitfall, since the Bragg spacings don't necessarily map on to conventional resolution. But it would fit the 1.5 Ang estimate. Also, resolution would depend a lot on

[ccp4bb] phosphates

Doe any one know what resolution is needed to distinguish phosphate from carbon in a difference map?

Re: [ccp4bb] "Atomic resolution"

I tell people it is when your resolution is less than the bond length that connects the two atoms. On Thu, Jan 11, 2018 at 1:59 PM, Thomas Edwards wrote: > Dear Jacob, > > Ah... this old chestnut! > > Current EM people say that they are at atomic resolution because they are > building atomic mode

Re: [ccp4bb] "Atomic resolution"

In the “good old days” we used to refer to “atomic resolution” as higher than 1.0 Å (or more specifically, at least 0.8 Å resolution), e.g. the resolution obtained by most small molecule structures, where you get at least 10 times the number of observables per refined parameter, and thus could d

Re: [ccp4bb] "Atomic resolution"

The reason behind this query is that I want to illustrate the power of prior knowledge in data analysis. I want to say something like “even though atoms cannot be directly observed at worse than X resolution, which represents Y% of the PDB, all of these data sets have been fit correctly with ato

Re: [ccp4bb] "Atomic resolution"

Dear Jacob, Ah... this old chestnut! Current EM people say that they are at atomic resolution because they are building atomic models (naive??). I have been criticised in the past for using the term with say 2.2A diffraction data. By co-authors and reviewers alike. When I was young and naive.

[ccp4bb] "Atomic resolution"

Dear Crystallographers, Has there been a consensus as to what is meant by "atomic resolution?" Seems like the term is taken by various practitioners to mean different things. A related question: at what resolution are atoms "visible" using only the data? I have an empirical feeling that this wo

If anyone reading this is in a position to help, could something be done about the extreme unreliability of the audio? It keeps cutting out, and there is a limit to how many times we can text someone who is physically there to go and ask for it to be fixed. Thanks, Peter. On 09/01/18 10:39, C

Thanks for this reply I exported http_proxy... It is not like the ccp4um does not have a connection. It can determine that there are updates and downloads and installs small updates (up to a handfull of MB) without a problem. Larger updates start downloading at ridiculously low speeds, then suddenl
