Re: [phenixbb] autosol w/ "no merge original index"?
by Tom Terwilliger 19 Dec '07

Hi Bryan, Yes, "No merge original index" files should work fine. This file should be converted by the autosol wizard to premerged scalepack during the run. In your case this seems to be so as the file header that is being read during the middle of the run 1 -987 86.052 86.052 132.608 90.000 90.000 90.000 p41212 is premerged scalepack. Now what does not make sense is the error message "You have set the keywords readdenzo and unmerged". I am not sure where that has come from. I just ran a SAD dataset to test this with an unmerged original index file, and it ran fine for me. If this doesn't help, could you send me (terwilliger(a)lanl.gov) your input script and datafile ( or even the first 1000 lines of the datafile) and I can try to debug it.

autosol w/ "no merge original index"?
by Bryan W. Lepore 19 Dec '07

19 Dec '07

phenix 1.3b of 21-10-2007 confusion w/ "no merge original index" data file in phenix.autosol. this should work, right? caveat - the 'nmoi' hkl is actually from scala, but that usually is fine w/ e.g. solve-2.13. 'nmoi' requires declaration of cell='(numbers)' on command line. phenix.autosol seems to go through all the usual checks fine, then reports (in AutoSol_run_2_/LAST.LOG): ".... The error seems to be at line 0 Here is what the first few lines of this file look like: 1 -987 86.052 86.052 132.608 90.000 90.000 90.000 p41212 You have set the keywords readdenzo and unmerged Please check whether you should have set readformatted or readtrek or premerged ...." ... 'readdenzo' and 'unmerged' are just right for 'nmoi' files. etc. -bryan

Re: [phenixbb] MTZ intensities interpreted as amplitudes by autobuild command-line versions up to 1.3b/rc6
by Thomas C. Terwilliger 19 Dec '07

19 Dec '07

Hi again Peter, Yes, the AutoMR wizard (any version) will run correctly with input MTZ data that are intensities. However all versions up to now will pass this MTZ file on to AutoBuild without conversion to amplitudes and it will be incorrectly interpreted by AutoBuild. Note that this only applies to MTZ files. Any other source of amplitudes/intensities doesn't cause any problem. If you run from the GUI, you will have the chance to set the correct columns in AutoBuild, if amplitudes are available in your data file. From the command_line, for existing versions, you would need to say when you run AutoMR: input_labels='F SIGF' (or whatever your amplitudes are in this MTZ file) All the best, Tom T > Hi Tom, > > What about the AutoMR wizard.

after_autosol
by Bryan W. Lepore 19 Dec '07

19 Dec '07

using phenix 1.3b of 21-10-2007, trying `phenix.autobuild after_autosol` : how does one identify the "highest-numbered AutoSol run", and that it is completed? what does `phenix.autobuild` want for such a solution e.g. in terms of files/directories? or does `phenix.autobuild after_autosol` need to be included in the command at the time when `phenix.autosol` is submitted? phenix.autobuild reads a lot of params from my AutoSol dir, but apparently no solutions -- even though `phenix.autosol show_runs` shows one. -bryan

chain definition in phenix
by Kornelius Zeth 19 Dec '07

19 Dec '07

Dear all, I'm trying to refine/rebuild a structure of 48 identical chains. In Refmac the small letters a, b, c and 0 1 2 for the chains work quite well and are distinguished. However that does not apply to Phenix which sees A equal to a. What might be the solution to use?

Re: [phenixbb] Resolution Limits in the transition from AutoMR to AutoBuild
by Tom Terwilliger 17 Dec '07

17 Dec '07

Hi Dale, Thanks for the notes! Here is what is supposed to happen: the autobuild wizard keeps all the data you supply. resolution=2.2 will set the resolution of model-building and density modification and refinement refinement_resolution=2.3 will set the resolution for refinement to 2.3 instead of the 2.2 defined by resolution=2.2 There is as you guessed a bug however somewhere in the communication between the autobuild wizard and phenix.refine, so the refinement_resolution did not get passed properly. I will fix that... Thanks! -Tom T .

A Small Problem with Atom Types in AutoBuild
by Dale Tronrud 17 Dec '07

17 Dec '07

The probe model in my MR project comes from a Shelxl refinement, and the .pdb file does not contain atom types at the end of each ATOM statement as modern .pdb files do. I have magnesium atoms in my model and the atom names for these atoms are "MG" and are properly shifted one space to the left of place where atoms with single letter element symbols lie. Phaser has no problem with this .pdb file. Resolve, however, considers this to be a fatal error. Opening MR.1.pdb and reading coordinates Warning...unknown atom type "M " ...this may indicate characters in columns 77-78 of this PDB file that are not the element ID. This and all similar labels ignored Failed to read line in PDB entry The PDB line is: ATOM 2953 MG BCL B 1 26.429 2.746 -11.155 1.00 12.03 Sorry could not read model file MR.1.pdb Seems a little harsh to me. Especially since the error message doesn't make it back to the log file monitored by the Wizard. I was confused about what was causing the wizard to stop until I dug into the other files in the AutoBuild directory. Earlier in the log file the program worries about my atoms "NA" and "NB" but does conclude that they are nitrogen atoms. In the future I'll work with .pdb files with the extra atom types at the end of the line. Dale Tronrud

Resolution Limits in the transition from AutoMR to AutoBuild
by Dale Tronrud 17 Dec '07

17 Dec '07

The structure factors that I downloaded from the PDB for my little MR project contains both reflections behind the beam stop and reflections of higher resolution than even the original authors would use. When setting up the MR I entered the more restrictive resolution limits into the Wizard and Phaser appears to have obeyed. As near as I can tell from the log files, however, Resolve is using all the data in the rebuild. I am including a copy of the log file from the "best" refinement. I would prefer that only data between 30 and 2.2A were used but it is clear that the refinement is, at least, monitoring the fit to all the data. I am presuming that the program is refining against the same data it is monitoring. I would like to suggest that either the log file be clearer about the resolution limits it is actually refining to, or the plumbing that passes the resolution limits from the AutoMR wizard to the AutoBuild wizard be checked. Dale Tronrud P.S. That's all my problems... For now. The project I'm working on is cursed and brings out the worst in all the software I have used.

Hi again Dale, I spoke too quickly...it is not so easy to change the code as I hoped. However here is a work-around that may be preferable anyhow: 1. Remove your ligand from the PDB file to be rebuilt and put it in "lig.pdb" 2. add to your commands for autobuild: input_lig_file_list=lig.pdb This will put all the contents of lig.pdb at the end of all PDB files just before refinement. All the best, Tom T Hi Dale, Your hypothesis: "I suspect that the coder assumed that all alternative conformations mutually exclusive and involve the same subset of the residue." is quite correct. (I am the coder in question). I think that I may be able to fix this particular problem and take care of the cases you have in this structure by simply allowing all conformations of ligands in the input file to be kept during rebuilding. With luck, this will work and will be in the final 1.3b version due out very shortly. The autobuild wizard still will not know how to build multiple conformations into a structure. For the time being it will have to stick with building one conformation. Thanks very much for the suggestion! -Tom T > Hi, > > I desire to resolve a crystal, who's structure factors I've downloaded > from the PDB, using my new high resolution model of this protein from a different species.

Since the probe is from a high res refinement it contains quite a few groups with alternative conformations.

A Bchl-a molecule is much larger than an amino acid so it is quite possible, and reasonable, for one part to have a "A" and "B" pair of conformations, another part to have a "C" and "D" pair, and somewhere else for there to be a "E" and "F" pair.

I would prefer a more careful analysis to uncover the fact that "A" and "B" go together, and "C" and "D" go together. If there is a need to reduce the complexity of the model, (and I would prefer that all the alternatives make it through to the end) could the program keep "A", "C", and "E", or whatever makes sense for any particular residue? Better yet, instead of always keeping the first alternative of a set, could it keep the one with the highest occupancy? > > I'm using phenix-1.3b-rc6 on a Fedora 6 PC. > > Thanks, > Dale Tronrud >
