RESOLVE density modification
by Mark A Saper 09 Mar '15

09 Mar '15

I am trying to run RESOLVE density modification with the output of a SAD Phaser run (dev-1965). There are 3 input files: high resolution/experimental F’s and I’s, map coefficients and phases, and sequence. I consistently get this error: … ******************************************************************************** Failed to carry out AutoBuild_set_up_build: For finding NCS from sites an MTZ file is required ******************************************************************************** I do not know which MTZ file is being referred to. I have tried entering NCS as blank, 1, or turning it off in the NCS… options panel. I also tried including the substructure PDB file. Any suggestions? -Mark _________________________________ Mark A.

hi, i need the correlation coefficients map/residues for a publication, which command should i use to get phenix.get_cc_mtz_pdb to take into account the neutron scattering tables? seems it uses the x ray tables by default. i can not find it on this page: http://www.phenix-online.org/version_docs/1.8.3-1472/get_cc_mtz_pdb.htm#anc… many thanks for your reply. -- Dr. Maxime Cuypers

a sharp rise of R-free in resolution bin
by Singh, Bishal 25 Feb '15

25 Feb '15

Hello everyone, I am refining a structure at 2.3 A resolution. R-work/R-free is 26/31 and is not reducing further. When I looked into the resolution bin, I notices a sharp rise of R-free between resolution range 2.5-2.6 A (marked in figure below). However R-work is fine. I am doubtful of reducing the resolution to 2.5 A or lower. Please suggest me your opinion. Your words will be highly appreciated. With regards, Bishal Singh PhD Student University of Heidelberg, Germany

How to define a disulfide bond between symmetry related molecules in phenix.refine
by Michael Hothorn 25 Feb '15

25 Feb '15

Dear all, I am trying to refine an intermolecular disulfide bond in phenix.refine. The disulfide involves Cys 188 in chain A and Cys 188 of chain B of a symmetry related molecule, with symop -X, Y+1/2, Z+1/2. There are two molecules in the AU, SG is P212121. I generated the following SSBOND entry in the pdb header: SSBOND 2 CYS A 188 CYS B 188 1555 3555 2.04 Based on this: http://www.wwpdb.org/documentation/file-format/format33/sect6.html the format seems fine, but the disulfide is not being recognized during refinement. Could someone point out to me how to correctly define this for phenix.refine. Thanks! Michael
