Re: [phenixbb] Resolution Limits in the transition from AutoMR to AutoBuild

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.

Re: [phenixbb] Problem with AutoBuild and Alternative Conformations

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.

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?

relative pathnames in .def or .eff files for phenix.refine?
by Schubert, Carsten [PRDUS] 14 Dec '07

14 Dec '07

Hi, would it be possible to add the option of using relative pathnames instead of full pathnames when .def and .eff files are written by phenix.refine? Would make transfer of files/projects easier. Cheers Carsten

Very very small Phaser Bug
by James Fraser 10 Dec '07

10 Dec '07

This is a fairly trivial bug, but I thought I'd report it anyway (I'm not sure whether the problem is with the phenix.automr (rc6 build) or with all phaser implementations (the one included is: 2.1.1 so I've emailed both lists): when running phaser in data that was scaled in P 31 2 1, I used phenix.automr to automate MR searches in all spacegroups that are indistinguishable by systematic absences with: phenix.automr template.pdb final_P3121.sca RMS=1 mass=17000 rebuild_after_mr=False copies=1 use_all_plausible_sg=True The program correctly finds the solution in P3221 with a log likelihood gain of 1000 vs 20 for P3121, everything is fine in the outputted PDB CRYST1 line and MTZ; however the log file annoyingly mentions the spacegroup for the last time with "Final space group:P 31 2 1" even though elsewhere in the log file it correctly lists "SpaceGroup of Solution: P 32 2 1". I've excerpted the log file below. If this is the intended behaviour and not a bug, then I apologize but find it quite counterintuitive.

automr with muti components (NMR models)
by ming lu 09 Dec '07

09 Dec '07

Hi everyones I am trying automr to solve the structure of my protein. It has three domains, each domain has NMR structure available. So the sequence identity of my search model is 100%. I tried use mutiple components as search models, but I had a hard time to obtain a interpretable solution. Any suggestions on the use of mutiple components as search models? or suggestions on how to use NMR structure as search models? Thanks for your help. Ming
