FEM maps
by Colin Levy 04 Jan '15

04 Jan '15

Dear All, when using FEM maps I notice that some solvent structure has clean (ish) 2Fo-Fc but not FEM density. Is this indicative of the water without FEM density being simply noise or is it more complicated than that? Many thanks, Colin Manchester Protein Structure Facility Dr. Colin W.

phenix.refine reference?
by Ulrich Baumann 04 Jan '15

04 Jan '15

Dear colleagues, a very happy New Year 2015 to all of you! Is there a specific reference for phenix.refine, please? Or is it ok if we cite Adams et al., Acta Cryst D66, 213-221 (2010) or the 2011 paper on Phenix? What about Xtriage? Thanks you very much for your kind help! Best wishes, Ulrich

a command on Phenix refine
by Wind Sui 04 Jan '15

04 Jan '15

Dear All, I use the graphic phenix.refine to do a refinement, and Phenix informed me I need to have a command "refinement.pdb_interpretation.clash_guard.nonbonded_distance_threshold=None". Will you please tell me by graphic phenic.refine, how can I input this command? Wind

a question related to phenix.refine
by Wind Sui 04 Jan '15

04 Jan '15

Dear All, After I finished a refinement by Phenix.refine and I closed the Phenix software, is any method I can get the exact phenix.refine window as the moment the Phenix.refine just finished the refinement? I mean by all the documents saved automatically by the Phenix.refine after it finished a refinement, how can I get the Phenix refine window once more, for the check of Log output, Run status, Results, MolProbity, Real-space correlation, Atomic properties, and sequence check?

Phenix Rosetta install

Dear all, I am trying to build the hybrid installation between Rosetta and Phenix using the rosetta.build_phenix_interface command Phenix version: phenix-1.9-1692 Rosetta version: rosetta_2014.35.57232 I have no problem in compiling rosetta alone but when I try to build the hybrid system I get the following error: False scons: Reading SConscript files ...

Cross-validation when test set is miniscule
by Derek Logan 19 Dec '14

19 Dec '14

Hi everyone, Right now we have one of those very difficult Rfree situations where it's impossible to generate a single meaningful Rfree set. Since we're in a bit of a hurry with this structure it would be good if someone could point me in the right direction. We have crystals with 1542 non-H atoms in the asymmetric unit that diffract to only 3.6 Å in P65, which gives us a whopping 2300 reflections in total. 5% of this is only about 100 reflections. Luckily the protein is only a single point mutation of a wild type that has been solved to much better resolution, so we know what it should look like and I simply want to investigate the effect of different levels of conservatism in the refinement, e.g. NCS in xyz and B, group B-factors, reference model, Ramachandran restraints etc. However since the quality criterion for this is Rfree I'm not able to do this. I believe the correct approach is k-fold statistical cross-validation, but can someone remind me of the correct way to do this? I've done a bit of Googling without finding anything very helpful.

Mac backwards compatability
by Katherine Sippel 19 Dec '14

19 Dec '14

Hi all, I was trying to be a good child and update to the latest nightly build, but I noticed that the Mac options for dev-1893 and -1894 are all listed as OS X 10.9 rather than OS X 10.6.7+. I attempted to use the OS X 10.9 installer just to see if it would work (it does not). Is phenix no longer supporting older Mac OSs? I know you have more than enough OSs to keep track of, so there is no judgement in that statement. I am just trying to figure out if I am going to have to cave and begrudgingly update my OS. Thanks, Katherine -- "Nil illegitimo carborundum"* - *Didactylos
