Re: [ccp4bb] Good 3D Monitor for Molecular Modelling

Hi Matt, I guess you are talking about hardware. For a year or so, this should have become quite cheap. A recent Nvidia Geforce card, a 120 Hz 3D Monitor and a 3D vision kit should do the trick. However, personally I only have experiences with the "professional" NVidia quadro grafics card series.

Hi Fred, are you using the output from vina directly (I think it is called pdbrq)? If so, you could try converting it to mol2, before loading it into pymol. Cheers, Johannes Am Do., 1. Apr. 2021 um 15:59 Uhr schrieb Robbie Joosten < robbie_joos...@hotmail.com>: > Hi Fred, > > I think this is a

Re: [ccp4bb] ccp4 package manager

Dear Edwin, I had a similar problem and it had to do with our institutions proxy settings. The proxy settings in ccp4i did not affect the updater settings. I could not resolve it and always had to manually download the full update package. Cheers, Johannes 2016-11-29 21:02 GMT+01:00 Edwin Pozha

Re: [ccp4bb] Coot and Pymol 3D in Quadro M4000 Graphics Card under Windows 10

Hi Xiao, did you try manually changing the Hz in the nvidia system control panel? It is somewhere under Resolution-> adapt (or something like that, sorry, I don't have an english version). There you can change the frequency. If it doesn't work and you only see a black screen, the system switches b

Re: [ccp4bb] intermolecular dissulphides

Dear Eleanor, sorry for the late reply. I found a similar case (id: 2OEF, Cys 92). I mutated the Cys to Ser, but it did not change anything (xtal conditions and quality remained the same). In solution the protein is a monomer. However, adding 1 mM DTT resulted in a significant increase in crystal

Hi Adriana, when I am at home, I do the following. Use zinc structure search ( http://zinc.docking.org/search/structure) to generate a smiles code (or any other website that can do this), then take that code to phenix elbow and generate the ligand including cif. Other softwares that can do this of

Hi, I had the same problem once. Some chemistry programs are not really good at exporting to pdb. Check the file format definition of pdb files, here: ftp://ftp.wwpdb.org/pub/pdb/doc/format_descriptions/Format_v33_A4.pdf Most interesting for you is probably pp. 174. Also make sure, there is an "EN

Re: [ccp4bb] suggestion on protein crystallization optimization from phase separation

Dear Joseph, You have probably already done so, but have you tried in- or decreasing your protein+DNA concentration? I had a similar problem with proteins that were concentrated too low. I had to increase protein and decrease Ammonium sulfate (precipitant in my case) concentration. Cheers, Johann

Re: [ccp4bb] 3D stereo and pymol

Hi Christine, as far as I know, it does not work at all with Geforce cards. The Nvidia drivers do not support windowed quad buffered GL, which you need for coot/pymol. It does not matter whether you use Windows or Linux. But this is based on my personal experience from around Oct. 2016. Maybe some

[ccp4bb] definition of "apo" and alternatives?

Dear collegues, a while ago, there was a discussion in the board on the term apo-structure as a way to descibe a native, free, or unbound protein (no ligands). I think the conclusion was that an apo-form is a halo enzyme lacking a cofactor and should not be used as a substitute for "unbound". We w
