[ccp4bb] PhD Bayesian protein structure prediction

2014-05-06 Thread Thomas Hamelryck
Hi everybody, One PhD position is available in the group of Assoc. prof. Thomas Hamelryck, Copenhagen, Denmark. The subject is inference of protein structure using state of the art probabilistic methods. Knowledge of Bayesian probabilistic modelling, machine learning and C++ is a strong plus.

[ccp4bb] Script for Comparing Structurally-Similar Proteins

2014-05-06 Thread Keller, Jacob
Dear Crystallographers, In a former lab we had a script which would read DALI output, automatically download the structurally-similar proteins, superimpose them, and color by regions superimposed. That was in the days of O. Does anyone have a similar-functioning script for CCP4MG, pymol, or

Hi Tobias, We use LabTrove: http://www.labtrove.org/ Pros: Relatively easy local install Revision control Ability to attach any file Cons: clumsy blog formatting does not lay eggs. Regards, Dmitry It is a bit clumsy being based on a blog engine and does not lay eggs… But it works

[ccp4bb] Refining Metal Ion Occupancy

2014-05-06 Thread Chris Fage
Hi Everyone, In my 2.5-angstrom structure, there is negative Fo-Fc density surrounding a metal ion after refining in Phenix. From anomalous diffraction I am certain of the metal's identity and position in each monomer. Also, the ion is appropriately coordinated by nearby side chains. Should I be

[ccp4bb] SOS from last century!

2014-05-06 Thread Carter, Charlie
I need help with a problem whose dimensions I perceive, but cannot surmount. It appears to be very important for me to re-make an illustration I made long ago using molscript. For various reasons, I cannot think of a way to do this with Pymol. I want to highlight active site residues by

Dear Charlie, I still use molscript quite a bit, it is not so old fashioned as you might think. Raster3D is even in the standard repository of Debian. You need to use the command line option '-r' in order to create Raster3D output. You can use the pipe molscript -r -in your_molscipt.inp |

Hi, I love using the ESCET algorithm developed by Thomas R. Schneider, it calculates error-scaled difference distance matrices, identifies domains very precisely, generates pml of aligned and coloured molecules... I just love it. More info: http://www.ncbi.nlm.nih.gov/pubmed/10818348

2014-05-06 Thread Steven Herron
Refining the occupancy will help your R-factor and flatten your density, but you need to be careful to also refine the B-factor of the metal ion. Don't refine both the occupancy and the B-factor during the same run (the two are correlated at this resolution), refine the occupancy of just the

I have used CNS before, but not for this sort of refinement. I see in the bindividual.inp file that I can select atoms to be included--it is defaulted at known and not hydrogen. Do you know the proper nomenclature for selecting a Zn ion in chains A and B? Thanks, Chris On 5/6/14, Steven Herron
