how-to change resolve keywords using phenix.multi_crystal_average
by Bjørn Panyella Pedersen 09 Jun '10

09 Jun '10

Dear board I am doing a difficult case of density modification. I get good results using resolve after optimising some keywords. I now want to use multicrystal averaging. This works ok in dmmulti, but I would like to combine it with resolve. For this I have tried phenix.multi_crystal_average, which also runs phenix.resolve, but it uses default keywords for resolve, and I can't find documentation on how to change these keywords. Current maps from phenix.multi_crystal_average are worse that the optimized resolve maps, and I believe this is because of the default resolve settings. Is it possible to control resolve keywords using phenix.multi_crystal_average? And how can I do it?

A couple of questions regarding twinning
by Pietro Roversi 03 Jun '10

03 Jun '10

Dear all, A couple of questions regarding twinning: 1. The structure I work with has multiple twinning domains (4 to be exact, with pseudo-orthorhombic 222 symmetry induced by twinning in P1). I feed the autobuild script the operators using a keyord: input_files.refine_eff_file_list=mytwinrefinement.eff (see attached file) but only the last one seems to be used. Do I guess correctly that there is only provision for two domains adn therefore the last twinning definition overrides any previously defined one? If so, is there a way of specifying and using multiple twinning domains/operators? 2. Output structure factor amplitudes: are they detwinned? Are they detwinned before the density modification in resolve? and during it? Thanks for any clarification/suggestions Regards Pietro

Re: [phenixbb] NAG-NAG description

Thanks for the feedback. I would like to refine a NAG-NAG chain attached to residue Asn122 in my structure. There are 5 identical subunits. Could you verify my .params file? I get the following error: Empty atom selection refinement .pdb_interpretation.apply_cif_link.residue_selection_1="chain A and resname NAG and resid 122" Thanks. -Chris On 31 May 2010, at 21:34, Georg Mlynek wrote: > Dear Chris, this did it for me. > > > Create a file which you can call whatever you want even the extension > doesn't matter.

segmentation fault
by Harry M. Greenblatt 01 Jun '10

01 Jun '10

BS"D Dear All, We had the phenix 1.6.1 GUI running on a fedora core 12 machine; it was thought, for different reasons, that a kernel upgrade would address certain issues unrelated to phenix. The machine is now running 2.6.32.12-115.fc12 (64 bit) and phenix now gives a segmentation fault. Any suggestions?

Weight optimization
by Jianghai Zhu 28 May '10

28 May '10

Hi, I am using the optimize_wxc=true and optimize_wxu=true in my last refinement. The R and Rfree went down but the RMSDs were way too large. I wonder if phenix.refine still targets the geometry when it optimizes the R and Rfree. Here are the results from almost two identical runs except the weight optimization. 1) optimize_wxc = False optimize_wxu = False wxc_scale=0.08 wxu_scale=1.66 results: R=0.2294 R-free=0.2709 angl=1.087 bond=0.006 2) optimize_wxc = True optimize_wxu = True wxc_scale=0.08 wxu_scale=1.66 results: R=0.2141 R-free=0.2628 angl=2.894 bond=0.033 I am using the dev-412 version. Thanks. -- Jianghai

offtopic: Problem with Pymol showing maps
by Tatyana Sysoeva 28 May '10

28 May '10

Hi all, if somebody is still not on the memorial day weekend, I have a short question off-topic for Pymol-users I have several maps from Phenix and want to draw some pictures in Pymol. I am opening the files, renamed to ccp4 or map, or not, and all I am getting is just a box, which is not even a unit cell boundary. If you know some nice simple program to do nice pictures of the electron densities- share your knowledge please! Sincerely Tanya

Super: Rotation and translation
by J. Fleming 28 May '10

28 May '10

Hello, I've been using 'super' to align the c-alphas within one domain of two different models of the same protein while leaving the second domain to move freely. I can do this using: super (A and resid 1-100 and name ca), (B and resid 1-100 and name ca) What I would like to do is determine the rotation and translation of model B's second domain as it moves away from A's second domain. I can output a matrix after running super using: print cmd.get_object_matrix("A") How do I go from the matrix to an angle and distance? Thanks for any thoughts, Jon
