unknown parameters file format?
by Kyle Dolan 05 Aug '10

05 Aug '10

Hi all, I tried to create my own set of refinement parameters by copying sections of a .def file to a new file I called myrefine1.params. When I tried to use this for phenix.refine from the command line I received this error message: Sorry: Unknown file format: myrefine1.params What should I do? Thanks, Kyle Kyle T.

Re: [phenixbb] follow up on message 2: phenix.maps --Message: not implemented

Hello Pavel, The averaged kicked map looks great! I am able to see loop density that I could not see before. However, I still have one question: The kicked map were created when I put the map parameters in my custom_par file however, I was unable to run Phenix.maps in the command line. When I do this I get a message "Not implemented". I would like to create a ccp4 map for viewing in pymol without running refinement again. Do you know what could be causing this message? If I create "maps.params" by inserting the commands from the .def file Phenix does not recognize this file format. Any help would be appreciated.

r-work and r-free for specific resolution range(s)
by Kay Diederichs 04 Aug '10

04 Aug '10

Hi, is there a way to get the R-factor statistics from phenix.refine, for a specific resolution range, e.g. 2.5-2.6A ? The reason I ask is that I would like to specify the same resolution range as the data reduction program does. I tried with phenix.reflection_statistics x_map_coeffs.mtz x_data.mtz --low-resolution=2.6 --resolution=2.5 but with the default settings, phenix.refine writes 2FOFCWT and FOFCWT, but not FC . So it looks like I have to re-run phenix.refine and make it write out FC? Or is it easier to run phenix.xmanip for that purpose? thanks, Kay

Hello, I am trying to run AutoMR using a chain that is 1014 amino acids. The output pdb starts back at 0 once it reaches 1000. Is this a bug, or user error? Thanks, Meghan

XDS has 9 shells whose limits are calculated internally, and one overall. For XSCALE, one can specify up to 20 RESOLUTION_SHELLS . In the meantime, I resort to sftools <<EOF read x_f_model.mtz Y select col R_FREE_FLAGS=0 correl col FOBS FMODEL resolution 2.6 2.5 shells 1 select all select col R_FREE_FLAGS=1 correl col FOBS FMODEL resolution 2.6 2.5 shells 1 stop y where x_f_model was written by phenix.refine . thanks, Kay

Thanks Pavel! I will wait and see what Ralf says regarding defining the symmetry operator. If I am using the GUI for phenix.refine should I create a new file with the bond definition you mention and include it as one of the starting files or should I edit the Refine_*.eff file that gets created and insert it somewhere there? ___________________________________________________________ Joseph P.

Hi Ralf and Pavel, Unfortunately, Phenix didn't recognize a disulfide bond should exist between the sulfur atoms of DTT and the side chain sulfur atom of the cysteine residue in question. I position everything well in the Fo-Fc and 2Fo-Fc maps and ensured the two sulfurs were approximately 2.1 A apart. However, after refinement the DTT molecule moved so the two sulfurs in question where nearly 3 A away. Maybe this is because it is a mixed disulfide between a DTT molecule and a side-chain Cys rather then what most programs expect which is a disulfide between two Cys residues. Is it possible I need to define the complete chemical entity as a hetatm (the disulfide linked Cys residue? Is there a way to specify that a covalent bond should exist between the SG atom of the Cys in question and the S atoms of DTT with DTT lying across the crystallographic two-fold given its internal 2-fold symmetry?

DTT mediated disulfide crosslink across a crystallographic two-fold!
by Joseph Noel 03 Aug '10

03 Aug '10

Hi Phenix Users, I have found a beautifully ordered DTT molecule stretching across a crystallographic two-fold and linking two symmetry related cysteine side chains. Since part of this molecule sits on across the two-fold (special position) I will specify the occupancy as 0.5. I am hoping to get some information on how easy (or how difficult) it is to specify this arrangement in Phenix for refinement since it is covalent and sitting across a crystallographic two-fold (and presumably stabilizing the lattice). Will ReadySet build the appropriate CIF file if I build the DTT into the density and give it a 0.5 occupancy? Joe ___________________________________________________________ Joseph P.
