matt, can't offer much help, but have you tried to remove the ligand and try refinement? it would let you know if the pdb file or the presence of the ligand is the problem. at least let you would know where you should focus your attention. if all else fails, have you tried getting parameters for your ligand from the PRODRG Server and using that for inputing the ligand parameters into phenix.refine directly when you setup the refinement job? (I think i have done this before???) here is the website in case you aren't familiar... http://davapc1.bioch.dundee.ac.uk/programs/prodrg/ Again, Best of luck! cheers, nick -----Original Message----- From: Matthew Bowler <mwb(a)mrc-dunn.cam.ac.uk> To: phenixbb(a)phenix-online.org Date: Thu, 15 Mar 2007 13:00:42 +0000 Subject: [phenixbb] phenix.refine problems with my pdb Dear All, I am trying to run phenix.refine but I keep getting the message: Sorry: Fatal problems interpreting PDB file: Number of atoms with unknown nonbonded energy type symbols: 308 Please edit the PDB file to resolve the problems and/or supply a CIF file with matching restraint definitions.

matt, >>> Number of atoms with unknown nonbonded energy type symbols: 308 just curious, did you have 308 waters? as peter said, hard to determine exact problem without some files or examples to look at. also phenix does a good job with water picking, in my little experience. just one more question, when you do get the refinement to work, is your ligand(s) included with the protein model? just no waters, right? it wasn't completely clear from your message. if the ligands aren't included, i recommend adding it(them) back and see if refinement works. then if that works, try water picking within phenix. again, best of luck. cheers, nick -----Original Message----- From: Matthew Bowler <mwb(a)mrc-dunn.cam.ac.uk> To: noinaj(a)uky.edu, PHENIX user mailing list <phenixbb(a)phenix-online.org> Date: Thu, 15 Mar 2007 14:15:45 +0000 Subject: Re: [phenixbb] phenix.refine problems with my pdb Thanks for replies so far.... I removed all ligands and then waters - the waters seem to be the problem as the protein model is now refining, do they need to be treated/marked in a different way for phenix? Thanks again, Matt.

Few questions
by john kryst 15 Mar '07

15 Mar '07

Hi phenixbb !! I have few questions. 1. Is there any utility in phenix to write out pdb formatted (which is ready to deposit) output file.. like xtal_pdbsubmission utility in CNS. 2. In Autobuild wizard how to ask the program to use the Free R flags present in the file. It always generates new Free R flags during refinement. One general question. Does the rmsd estimation (for eg. rmsd_bonds ) depends on the program we use ?? I have been refining in CNS. then i used Autobuild wizard to build my model. when i went back to cns the rmsd of bond increased (0.0218 A). But phenix.refine says it it 0.007A. Thanks in advance for your kind inputs. regards john

Two groups per residue and multiple trajectories for simulated annealing
by Stephen Graham 03 Mar '07

03 Mar '07

Hi all, I am taking my first tentative steps into the world of phenix.refine with a somewhat problematic 3 A data set and I had a few questions that Google couldn't answer. I am running phenix.refine version 1.24.1b (intel-linux-2.6) from the command line. Firstly, is it possible to do 'grouped' adp refinement with 2 groups per residue (like the good old bgroup.inp of CNS)? Secondly, is it possible to specify multiple starting trajectories for simulated annealing? I often find it handy to do 10 runs of simulated annealing and overlay the output co-ordinates to see where the 'wobbly' bits are. Lastly, can the latest version of phenix.refine do SA omit maps? Thanks, Stephen P.S. My .def file is the default (from phenix.refine --dry-run) w/ the following changes: 86,87c86,87 < refine_adp_individual = True < refine_adp_group = False --- > refine_adp_individual = False > refine_adp_group = True 92c92 < simulated_annealing = False --- > simulated_annealing = True -- Dr Stephen Graham Nuffield Medical Fellow Division of Structural Biology Wellcome Trust Centre for Human Genetics Roosevelt Drive Oxford OX3 7BN United Kingdom Phone: +44 1865 287 549

> Anyone has any idea what is happening? Thanks. It is a bug that we've fixed already. We will release a new cci apps in the next couple of days that will include the fix. In the meantime, could you try removing the ANISOU cards (grep -v ANISOU xxx.pdb)? I think that should work around the problem. Ralf

Re: [phenixbb] input HA

Hi Morton, I'm sorry to make it difficult! Here are 2 formats that should work: 1. PDB format (I'm not sure why the one from cns failed...can you send me a line or two from that so I can make it work?): HETATM 1 SE SE 3 73.920 0.324 3.857 0.92 54.60 Se HETATM 2 SE SE 4 39.591 8.262 2.158 0.55 60.00 Se 2. Plain fractional xyz, with or without the word "xyz". For example see: $PHENIX/examples/gene-5-mad/sites.xyz : xyz 0.0271 0.8074 0.0657 xyz 0.0239 0.0116 -0.0965 Please let me know if this doesn't do it! -Tom T At 03:52 AM 2/13/2007, Morten Grøftehauge wrote: >Ok, I give up. > >What is the correct format for a heavy atom file >for AutoSOL?

Ok, I give up. What is the correct format for a heavy atom file for AutoSOL? I've tried both the outputs from FFT, CNS pdbs and sdbs and I've tried just putting them on a line like you do for SHARP: ATOM Br -0.0120 0.5731 0.2740 but none of them are accepted by Phenix.

CCI Apps
by Noinaj 27 Jan '07

27 Jan '07

Hi, Quick question. I am trying to refine occupancy of a ligand and was attempting to do this using the method outlined under the CCI Apps documentation for phenix.refine. a.. Refinement of one occupancy factor per selected group of atoms (group occupancy refinement): % phenix.refine data.hkl model.pdb strategy=group_occupancies \ refine.occupancies.group="chain A and resid 1"Yet, when I type the commands, I keep getting an error saying that something is wrong with my commands: strategy, group, etc. I have not (at least I don't recall) loading the updated CCI Apps and only have what was installed with Phenix 1.24b installation. Am I doing something wrong here or do I need to update the CCI Apps? Thanks in advance for all feedback!
