[ccp4bb] PhD Position in Structural Biology in Vienna

2008-11-14 Thread Kristina Djinovic Carugo
*PhD Position: Structural biology of protein-protein interactions in the muscle Z-disk* We are seeking a highly motivated PhD student to work on structural characterization of important protein complexes centered on major players of the Z-disk of striated muscle: alpha-actinin and filamin.

Re: [ccp4bb] X-Ray versus NMR Structure

although I agree with the statement below, I would say that X-ray crystallography also only generates a molecular model (not a structure). Rather than a structure, X-ray crystallography generates an electron density map. The quality of the model based in it depends on the quality of this

[ccp4bb] Baubles (re imosflm)

I have questions about baubles in general. I find that using firefox (3.0.4 windows) baubles logs do not open directly from ccp4i or imosflm and I get an error i is not a registered protocol (or c) which I think is the drive the file is on. However if I open the file in via open file then it

Dear Tassos, Bernhard and David, If I may push this humourous response (obviously tainted with crystallographic bias) a little further, I would say that my favourite mnemonic for the acronym NMR is N eeds M ore

I think we should slowly arrive in the 21st century and realize that methods are complementary to each other. I've never done NMR by myself only some xray stuff and attempts to merge EM data with xray almost 10 years ago to arrive at ab initio phases. Sure one can argue what information can

How about this one: Can't Refine Your Structure To Acceptable Likelihood Typical error bars on crystallographic data are ~5% (R_sym), but with very few exceptions the models in the PDB do not fit their corresponding observations to better than ~40% error (R_cryst for intensities). Gerard?
