[ccp4bb] Computational crystallography in 2024

2024-05-15 Thread Lucas Bleicher
read a PDB and mtz and calculate real space fit for an aminoacid, or generating symmetry neighbours from a asymmetrical unit PDB and its space group. How are people doing things like that in 2024? Cheers, Lucas Bleicher

[ccp4bb] OT - Software articles / databases

2009-01-09 Thread Lucas Bleicher
I've been compiling a reference database and I've just noticed that it's quite difficult to automatically retrieve references for most articles on crystallographic software. Has anyone noticed that? It seems that, for some reasons, articles on the Computer programs section on Journal of Applied

[ccp4bb] Model ensemble for x-ray crystallography

2008-03-28 Thread Lucas Bleicher
Some time ago I've heard about the idea of proposing an ensemble of models (as in NMR), instead of a single model for x-ray crystallography structures. If I remember correctly, this idea has been published somewhere. Can anyone tell me what article is that? Lucas Abra sua conta no Yahoo!

2008-03-07 Thread Lucas Bleicher
I've had a very good experience with MrBump: http://www.ccp4.ac.uk/MrBUMP/ Not only because of the program itself, which was able to find an unexpected template for the problematic chain (the first one was straightforward in Phaser), but also because of great support from Martyn Ron. It's

Re: [ccp4bb] Suggestion: Wiki -- was:Re: [ccp4bb] need help--Rfree is not decreasing

2007-07-22 Thread Lucas Bleicher
That would be a great idea. In fact, I keep on my mailbox dozens of great postings (most of them summaries) in CCP4 which would be very useful to everybody if there's an online resource, with information organized in topics. I would gladly copy them to this wiki. Lucas --- Kay Diederichs [EMAIL

Re: [ccp4bb] pdb-l: Sequence Location in Protein Tertiary Structure

2007-04-03 Thread Lucas Bleicher
By the way, I'll extend that question: the validation software Verify3D assigns not only buried state but also polar fraction and secondary structure, using the probability of finding given residues in the different environment defined when combining all this information to calculate a score of

[ccp4bb] change the B-factor for a residue

2007-03-23 Thread Lucas Bleicher
Is there a program in CCP4 with a command to change the B-factor of a single residue? I checked the documentation for pdbset and it seems to assign B-factors only for the whole molecule. What I'd like to do is plot a given residue property in a graphic software using the color by b-factor
