Re: [phenixbb] lower limits on grid spacing/binning

Probably, the original poster already got more than he bargained for, but for the records, a few more comments: > All FFT based structure factor programs require that the sampling > rates along each axis be even. I don't think this is true, unless I'm misunderstanding what "sampling rate" means. The FFT in phenix is based on FFTPACK (written in the 80s) which works for any number of grid points. FFTw also supports arbitrary gridding. > They may have other required factors > depending on the space group, but they will be happy to inform you > if you make a choice it doesn't like. They are also more efficient > when the prime factors of the sampling rates are small numbers. Try > to stick with multiples of 2,3, and 5 if possible. That's good advice. FFTPACK is fastest for transform sizes that are multiples of 2,3,4 and 5. The map calculation algorithms in phenix automatically take this into account. > All FFT programs will fail if you > sample your map courser than twice that frequency, as SFALL did for > you. This may be true for SFALL, but not for the FFT algorithms in the phenix libraries ($PHENIX/cctbx/include/cctbx/maptbx/structure_factors.h). The critical reference is: David A. Langs (2002), J. Appl. Cryst. 35, 505. As short as it is, this was an incredibly important paper. In retrospect, it is amazing that it took so long for someone to discover the trick. Ralf

lower limits on grid spacing/binning
by Terry Lang 30 Oct '07

30 Oct '07

Hey Everyone, I have been told by several crystallographers that the general rule of thumb for grid spacing when generating a map is one third the resolution (eg If your crystal structure has a resolution of 1.2 A, your grid spacing should be 0.4). Is there a mathematical reason why this ratio should be maintained or is this simply a holdover from slower computers with lower memory? More importantly for my application, is there a lower limit on how fine the grid spacing can be? In other words, is there a lower limit at which one is oversampling the data for a particular resolution? Any information and/or references would be greatly appreciated. Sincerely, Terry -- P. Therese Lang Post Doc Alber Lab, UC Berkeley

linking residues question
by Crystal K. Chuang 26 Oct '07

26 Oct '07

Hello all, I was wondering if there is a tool in RESOLVE that, when used through PHENIX, links up individual chains of residues and ties in symmetry related fragments so that, as a result, packs everything together to generate more of a globular unit? Many thanks, -Crystal

NCS interpretation
by Claudia Scotti 25 Oct '07

25 Oct '07

Dear list, I'm trying to undestand the NCS symmetry in a unit cell with 8 molecules (2 A resolution). The unit cell is almost orthorhombic (68.900 79.240 90.040 89.97 90.04 89.97), but only P1 + twinning worked for MR and for refining the structure (Rfree=0.22; Rcryst=0.18). The crystal simulated a P222 space group (the best seemed to be P21212), so I'd expect NCS axis parallel to . Now I've used phenix.simple_ncs_from_pdb to get the symmtery operators (see ouput below). I've read the manual, but I'm nevertheless finding it difficult to " see" the NCS axis. Any suggestions, please, on how to interpret the output, please, and "draw" the axis or on any alternatives on how to proceed? Many many thanks and a huge apology for the naive question (this is only my third strutcure...).

Re: [phenixbb] NCS interpretation

Hi Claudia, It looks to me like your ncs is almost exactly 222 symmetry, plus a centering. You can tell it is 222 symmetry because all the operators are zeroes except along the diagonal, and the diagonal elements are all 1 or -1 (or close to it). That means that the 4 unique operators go like: x y z -x -y z -x y -z x -y -z The 8 operators appear to be 2 sets of 4, with a centering operation... I made a little PDB file (at the end of this message) that shows the symmetry in these operators. If you run phenix.simple_ncs_from_pdb on it you should get back something similar to your operators. If you run the phenix.autobuild wizard one cycle of rebuilding (not rebuild_in_place) then it will try to find the most compact arrangement of your molecules, and it will also try to find the point group(s) of the molecule... in this case I think it will fail to find the point group though (as it failed with my test model made from your operators). Question: do your molecules pack nicely with this arrangement? -Tom T CRYST1 68.900 79.240 90.040 89.97 90.04 89.97 P 1 1 ORIGX1 1.000000 0.000000 0.000000 0.00000 ORIGX2 0.000000 1.000000 0.000000

Support for KNIME?
by Schubert, Carsten [PRDUS] 24 Oct '07

Hi, I was wondering if anybody has looked into integrating phenix with KNIME (http://www.knime.org/), as part of a pipeline for structure solution. Is this something the developers have looked into? Cheers, Carsten

problems with map quality, refinement and R/Rfree
by Joe Smith 19 Oct '07

19 Oct '07

Hi all, We have data sets for a protein-RNA complex at 3.2 A resolution. . The data belong to the space group I4122 and contains one molecule of Protein-RNA complex (300AA and 16nt; 66% solvent content) in the asym unit. We have managed to get phases using Se-SAD and the present model contains 60% of the protein atoms (250 residues many of them build as Ala) and almost complete RNA (16nt). We could not locate ~20 % of the residues (present in various loops as well as at N- and C-terminal ends). First 120 residues present at N-terminal end seem to have poor relatively main-chain density and almost no side chain density. RNA and 130 residues present at the C-terminal end have good electron density for main-chain as well as side chain. The solution seems to be correct as molecular replacement trials with this model gave same solution in Phaser, Molrep and AMoRe. Solution seems to be also correct because as expected one RNA strand present in asym unit pairs with another one coming from symmetry related molecule. We have checked data in space group I4122 with CCP4 (SFCHECK, cumulative intensity distribution), Yeates server as well as Phenix.xtriage. In all the cases it indicates no twinning. However if I process the data in lower symmetry space group it does indicate presence of almost perfect twin. We realize that this could be just because of processing data in lower symmetry space group and data in all probability may still be fine. The problem is now with refinement and model building. Refinement with CNS and Refamc gave considerably higher value of R and R free. In CNS1.1, refinement with small changes in the model some time leads to large shift in R and R-free value. Refmac: R=36; Rfree=47 CNS1.1: R=40-59; R-free=45-63 However in both the cases map looks more or less same (with reasonably good density for the main-chain as well as RNA) I tried refining with phenix.refine and there is some improvement in the R(34%) and Rfree(40%) values. I think may be robust bulk solvent correction incorporated in phenix.refine has helped in this case. However, I still see no improvement in the map quality for the first 120 residues. In the absence of any clear density I am unable to build any further. I feel N-terminal domain is bit flexible and may have overall poor density. I have used Se position as well as predicted secondary structure in assigning the amino acid in the map but due to few breaks in the N-terminal domain as well as poor density I am unable to assign any amino acid into the poly ala main chain. Frankly speaking, I do not know how to proceed further. I welcome any kind of suggestions which could help us in this case. Regards Joe

Hires input file problem
by Troy E Messick 11 Oct '07

11 Oct '07

Hi all, I seem to be having a problem specifying the labels for the Hires dataset for an Autobuild run. Here is my input script: input_data_file sharp.mtz input_labels 'Fdm' 'SIGFPsha' 'PHIdm' 'FOMdm' 'HLAdm' 'HLBdm' 'HLCdm' 'HLDdm' 'FreeR_flag' input_pdb_file ab.pdb input_seq_file seq.dat input_hires_file output.native.sca Here is the error from the AutoBuild.log file: ************************************************************ Failed to carry out AutoBuild_datafile_info_inputs: 'all_input_hires_labels' ************************************************************ I've tried to use the mtz file from the ImportRawData_run directory and specify the columns by substituting the last line in my input script file with: input_hires_file output_PHX.mtz input_hires_labels 'output.native' 'SIGoutput.native' which are the only labels I could find from mtzdump and that doesn't work either. What am I missing here? Any suggestions would be greatly appreciated. Thanks, Troy
