on Phenix's "Generate "Table 1" for journal"
by Smith Liu 23 Mar '15

23 Mar '15

Dear All, With the Phenix refine PDB and mtz file, I just prepared a "Table 1" for journal with Phenix. Here I find something special, which I hope I can get your advice. First, for the "Total reflections" and "Multiplicity", they are empty (no data given). Wil you please tell me why? Secondly, it writes, "Statistics for the highest-resolution shell are shown in parentheses". Suppose my crystal resolution is 2.5-45.6, then the the highest-resolution value should be 2.5, rather than 45.6, right? In addition, what is the diffrence between highest-resolution shell in the Table 1 and highest-resolution bin in the "Results" of Phenix refine? What is R-merge, R-meas,CC1/2 and CC*? I can get these data from MOSFLM output mtz file. But is my images were processe by HKL, which I have no experience, then how can I get the R-merge, R-meas,CC1/2 and CC*? I am looking forward to getting your reply. Smith

question related to phenix produced PDB file
by Dialing Pretty 22 Mar '15

22 Mar '15

Dear All, In my Phenix refine produced PDB file, I find in REMARK 3, there is a sentence "PHASE ERROR (DEGREES, MAXIMUM-LIKELIHOOD BASED): 42.3. Does 42.3 means 42.3%? Is it too high? I am looking forward to getting your reply. Dialing

error message in phenix refine
by Almudena Ponce Salvatierra 20 Mar '15

20 Mar '15

Hi everyone, I have merged 3 mtz files into one and done successfully Molecular replacement with it. However when I try to refine, I get the following error message: "cctbx error: merge_equivalents_exact: imcompatible flags for hkl (0, 0, 16) (mismatch between Friedel pairs). How can I fix this? Thank you very much in advance.

fixing rotamers with coot
by Benoît Masquida 19 Mar '15

19 Mar '15

Dear all, I am using Coot 0.7.2 and phenix 1.9-1692 on Ubuntu 13.10 and I have the following error message when I try to regularize zone, edit Chi angles or fix rotamer outliers. Error message :"Refinement setup failure. Failed to find restraints for : 'residue list' " Apparently a cif dictionary is missing that should be output by phenix to be used by coot. Does anyone has any idea? Thanks in advance. Benoit --

on Phenix refine
by Smith Liu 19 Mar '15

19 Mar '15

Dear All, Will you please tell me which strategy of Phenix refine is for reciprocal space refinement? In the log, I often see "XYZ individual (reciprocal space)", will you please let me know whether "XYZ individual (reciprocal space)" is caused by "XYZ coordinates" or by "Optimize X-ray/sterochemistry weight"?

on the eff file
by Smith Liu 19 Mar '15

19 Mar '15

Dear All, Someone told me from the refine eff file, I can know what is my strategy for my refinement. I have run 2 refines with the same input files, For one refine, in the graphical interface I have checked xyz-coordinates, Real-space, Individual B-factors, Occupanies, Optimize X-ray/sterochemistry weight, Automaticaly orrect N/Q/H erros. For the other refine, I only checked XYZcoordinates, Real-space and Autonomously correct N/Q/H errors. I have checked the eff files from the 2 diffrent refines, but I cannot find any diffrence in the eff file. Thus will you please tell me how to find the diffrence in the 2 eff files? Or my strategies for each refine was recorded in the other files? I am looking forward to getting your reply. Smith

phenix.development.optimize_model
by Colin Levy 19 Mar '15

19 Mar '15

Hi, I am running a Phenix development installation (dev_1977) and used the phenix.development.optimize_model option on a project of mine refined at 1.9Å. The output has certainly improved the R factors but I was curious as the refined model which is a rather globular structure has been refined utilising 17 TLS groups and anisotropic B factors. In its current state of development, how robust are these refinement choices and on what basis are they being determined? They differ somewhat from what I might have invoked manually?

Ramachandran results from Structure_comparison tool
by Emilia C. Arturo (Emily) 18 Mar '15

18 Mar '15

Hello, I've just run the Structure comparison tool for the first time using phenix 1.9-1692. All the results tabs--except the Ramachandran tab--have per-residue values throughout the length of the ~450-residue sequence; the Ramachandran tab has values only through residue 429. The sequence file included with the run contains 453 residues. Each of the pdb files input to the run have between 445 and 450 residues each. Throughout the length of each model, all models are 100% sequence-identical to each other and to the sequence file. Is it a known bug, that the Ramachandran values are not output for all the residues for which there are values in the other tabs?

labelit compatibility with mosflm
by Ursula Schulze-Gahmen 18 Mar '15

18 Mar '15

I tried to use LABELIT for the first time. I am using the version that comes with Phenix-dev-1951 (automatically installed through sbgrid). The program found some promissing solutions, but ends with the error: mosflm versions after 7.1.0 not supported It also doesn't seem to know ALS beamline 8.3.1 Any suggestions how to deal with this? Thanks Ursula -- Ursula Schulze-Gahmen, Ph.D. Project Scientist UC Berkeley, QB3 360 Stanley Hall #3220 Berkeley, CA 94720-3220 (510) 643 9491
