Hello Eddie, I believe this article from Robert Huber and coauthors was the first to discuss dynamical effects in a protein crystal:- Acta Cryst. (1980). B*36* , 621-627 Greetings, John On Thu, May 28, 2020 at 4:44

Re: [ccp4bb] PDB file header lines...

Hi Robbie Many thanks. I should tell the owners of the prediction server that they’re writing non-compliant files, in that case. So “BIDEN” is not compliant but “TRUMP” is? He’d like that… H > On 29 May 2020, at 16:02, Robbie Joosten wrote: > > Hi Harry, > > You need this: > http://www.wwp

Hi Harry, You need this: http://www.wwpdb.org/documentation/file-format-content/format33/sect9.html#MODEL Essentially you have to make sure a MODEL has a number and a closing tag. It is read as a real PDB record so you have to make sure it is correct BIDEN is not PDB compliant and will be eith

Hi Is there something about “MODEL ” lines (i.e. five characters followed by a space) in PDB files that is completely beyond the pale? I’ve got some PDB files from a protein structure prediction server based in the US that Coot fails to read and that cause QTMG to crash on my Mac. I’ve tracked

Hi Eugene, We recently had this with a student as well and at least in PDB format the files are salvageable by doing a simple search and replace from , to . Rather than going completely American, you can also just change the number format. In Windows 10 this is Settings > Time & Language > Dat

Dear Nadine, Many thanks for sharing your project with me on CCP4 Cloud. The reason for Refmac failure is absolutely clear: the previous Coot job exported PDB file, using commas (wie im besten Deutsch) instead of periods (as we would expect in best English) for all float-point numbers. You can see

Hi Tim You could send out an SOS to some of the other authors in the same issue, who might have kept a copy - several are “regular" posters on this forum, e.g. Sacha Urzhumtsev Gerard Kleywegt Eleanor Dodson There’s a good chance they’ll be stuck at home at the moment

Hi Bernhard, "Like comparing these map regions, excluding intrusion of a solvent mask, etc.": You didn't say much about the context.. So I'd say Polder map approach comes to mind first based on these keywords. Next is "map comparison" ( https://doi.org/10.1107/S1399004714016289). If none of the
