[ccp4bb] Postdoc position, structural biology, University of Cambridge, UK

Dear structural biologists, We have an opportunity for a postdoctoral researcher in my lab in the School of Biological Sciences, Department of Pathology, University of Cambridge, UK. The successful applicant will continue our work on bacterial multidrug resistance pumps, (e.g. see our

How about including all of this stuff in refinement? Only adds another ~10-100 [restrained] parameters… JPK + Jacob Pearson Keller Research Scientist / Looger Lab HHMI Janelia Research Campus 19700 Helix Dr, Ashburn, VA 20147 Desk: (571)209-4000

I agree that accurate and complete image header information is useful, but not universal. How about a routine similar to dials.discover_better_ experimental_model? W. On Wed, Jan 24, 2018 at 10:12 AM, Engin Özkan wrote: > Dear all, > > I have to agree with all sentiments

[ccp4bb] BCA spring meeting

Dear all, The British Crystallographic Association (BCA) Spring Meeting is taking place this year at the University of Warwick from Monday 26th to Thursday 29th March. There are already a number of great talks finalised for the meeting, and the deadline for further abstract submission is

Re: [ccp4bb] Issues with latest XDS (20171218)

Dear all, I have to agree with all sentiments stated, and I have definitely seen the value of restraining distance values in weak and anisotropic data, which is great for those of us who deal with such data on a regular basis. However, I also just went through a search of all refined

Re: [ccp4bb] Issues with latest XDS (20171218)

Dear Clemens, dear Kay, I absolutely agree with your statement regarding responsibilities. Unfortunately, for a user of a synchrotron beamline, it is hardly possible to _know_ that the distance (or any beam or camera parameter) provided by the beamline software is in error. In the end

Re: [ccp4bb] Issues with latest XDS (20171218)

Dear Oliver, yes, there are other changes to the parameter refinement procedure within XDS as far as I understand. These were introduced to robustify XDS processing (and parameter refinement) when encountering very poor datasets, cases where the crystal moves out of the beam in certain

Dear Kay, thank you ver much for the (as always) detailed and nicely explained answer. However this brings up some questions for me: 1. Could you please tell me how the "correct high-resolution cutoff" will effect the data processing in the INTEGRATE CORRECT step. In other words what will

Dear Colleagues, I would like to draw your attention to the position of the Director of Vienna BioCenter Core Facilities: */The Vienna BioCenter (VBC), /*/http://viennabiocenter.org/ / */,is one of the leading multidisciplinary biomedical research centers in

Re: [ccp4bb] Issues with latest XDS (20171218)

Dear Kay, Thanks for the quick reply. Let me answer your questions: a) Recycling of geometry parameters is certainly worth trying, although in our experience it rarely yields large improvements. Obviously, XDS used to do a pretty good job in default mode. In the latest version, however, since

Re: [ccp4bb] building into EM map

You could look at the CCP-EM software http://www.ccpem.ac.uk/download.php which includes CCP4 programs adapted to cryoEM (e.g. allowing input of cryoEM map). There is a range of possibilities from rigid body fitting of components, flexible fitting or de novo building. At 4 A, you may struggle
