Re: [ccp4bb] ipmosflm not connecting to XQuartz on Mac.

Hi Francis It works okay for me on OSX Mavericks when I use the “official” Mosflm build rather than the CCP4 one (choose the “X11” option when downloading). I don’t think the CCP4 build of Mosflm includes the X11 GUI (since we’ve been trying for many years to wean people off it…). I’m

Re: [ccp4bb] ipmosflm not connecting to XQuartz on Mac.

I had a similar problem with CCP4 generally after a recent computer upgrade. Re-installing xquartz worked for me, because some components had seemingly become deleted. HTH Mark On 15 Apr 2014, at 21:54, Francis Reyes francis.re...@colorado.edu wrote: Hi all, Anyone having issues

[ccp4bb] Studentship in Crystallography and Parasitology

Applications are invited for a three-year University of Leeds 110-year Anniversary Ph. D. studentship to work in the Goldman and Muench groups. The project will involve structural and functional studies of integral membrane pyrophosphatases, focussing on ones from pathogenic parasites such as

[ccp4bb] Rmerge, Rmeas, I/sigma, Mn(I/sd)

Hi, in the Rupp book the following relation is reported (on pag 415): Rmerge ≈ 0.8/I/σ(I) referring to a relation of the linear merging R-value with the signal-to-noise ratio. in a 2006 CCP4bb, Manfred Weiss reported: Rrim (or Rmeas) = 0.8*sd(i)/I so, First question: is it Rmerge or Rmeas

[ccp4bb] Validation reports for all X-ray structures in the PDB

Hi all, You may not have noticed, but 19 March 2014 was VR Day - the day that new style wwPDB validation reports for all X-ray structures were made publicly available - see http://www.wwpdb.org/news/news_2014.html#18-March-2014 The validation-related files for individual X-ray PDB entries

Re: [ccp4bb] regarding TLS records

Thanks Pavel. I was a little tired from an overnight Synchrotron run when I wrote that. Lesson: Stay off the internet when you are tired. Haha. I forgot that the TLS groups would be assigned per chain not per molecule. Thanks for the correction. I didn't know you could run find TLS groups as part

[ccp4bb] GRC Diffraction 2014 Instruct fellowships

Dear all, Unfortunately something went wrong in email archiving, and I recall receiving more applications from specific people, than what are now in my mailbox. May I kindly ask the people that did send an application, to re-send me their PDF file by reply to this email? Sorry again to

Re: [ccp4bb] Rmerge, Rmeas, I/sigma, Mn(I/sd)

The 2006 Weiss expression - I guess from the context- is for a single reflection h measured N times (and then is identical to my 8-23) while (8-24) is valid for the Rmerge (defined in 8-15) of averaging over a shell with h reflections each measured N times , which also explains why the two
