phenix v1.4-3 and NX
by Jesper Lykkegaard Karlsen 10 Jan '09

10 Jan '09

Hi, After upgrading our workstations to phenix v1.4-3, the user started having problems connecting to the machines through nxclient. The login ended up with a black screen on the client and absolutely no error messages on neither client nor server. The problem seemed to come from setting up the global environment for phenix (phenix_env.sh). I narrowed the problematic statement down to this: /if [ "$PHENIX_MTYPE" = "unknown-unknown" ]; then exit 1 fi/ Although "$PHENIX_MTYPE" = "intel-linux-2.6-x86_64" when logged in, somehow the "nx user" gets "$PHENIX_MTYPE" = "unknown-unknown" when it logs in, through it's authorization key, to establish the users session. To make a already to long story short. The problem can be fixed by commenting out the problematic statement above. And one question to the developers: Could this be avoided in the future? Perhaps give a warning instead off exiting completly! Sincerely Jesper -- Jesper L.

fixing a partial solution of mol. rep.
by chern 07 Jan '09

07 Jan '09

I am doing a molecular replacement. There are two types of protein molecules in the crystal. One type is forming a hexameric core; there are 6 molecules of the second type that I need to locate. I found a solution for the hexameric core, but the other 6 molecules are difficult to find. 1. Can I fix the solution for the core, so that I don't have to find it every time. The other inconvenience with that is that the origine is different for every new run. If I fix the hexamer, then I fix the origine. It's important to me to compare different runs of MR. 2. Some of the six other molecules that MR finds are not the closest to the core. How can I request to output the closest molecules? Maia

TRIED resolve ...NEED A BIGGER VERSION... message
by Ben Eisenbraun 05 Jan '09

05 Jan '09

Howdy Phenixians, One of my users is running phenix.autobuild, and while it seems to run okay, the output contains this warning: TRIED resolve ...NEED A BIGGER VERSION... Looking through phenix/phenix/autosol/run_resolve.py, it seems like this is an informational message, but I'm not sure, so I figured I'd ask. Is this actually an error? This is phenix-1.3-final on OS X 10.5. Thanks. -ben -- Ben Eisenbraun Structural Biology Grid Harvard Medical School http://sbgrid.org http://hms.harvard.edu

Selection of structure factors for DM
by Graeme Winter 18 Dec '08

18 Dec '08

Hi Folks, If I am using phenix.autosol for my phasing and dm, is there a way I can specify the "native" FP to use for phase extension? What I would like to be able to do is use a named wavelength for this rather than a synthetic data set composed from all input data... I used to do this with resolve by cadding in the chosen columns (F, SIGF) after solve and then telling resolve what columns to use. Would be cute to be able to not do this! Am running from the command line interface. Thanks, Graeme

Thanks for the reply. I think I didn't explain myself properly, of course I want to do bss, but we have noticed that previous versions of phenix (1.24 I think) did bss once per macro cycle and now with the newer versions, we get the same plus a final bbs cycle at the end of the whole process -shown in red- Is that final cycle introduced by default in the newer versions?

Thanks Ralf, You were right. I found that my .log file has Anomalous flag:True. As it was pointed out, my mtz file was came from ccp4 where it uses anomalous data by default. Another small wondering is about differently automatic(?) resolution pick up: my refmac assigned resolution range between 1.48 and 54.23 whereas my phenix.refine set it between 1.363 and 31.041 by default. Also while the refmac provides both entire and high resolution bin completeness, the phenix only gives a whole completeness. Is there any way I can investigate high resolution bin completeness? and why I have different resolution ranges by default without specifically assigning them? Thanks again.

Hi Rupert, Thank you very much for the files! I found a simple, universal trick to "do the right thing", not just in phenix.refine. This will be in future releases. Ralf

Completeness issue by phenix
by Young-Jin Cho 15 Dec '08

15 Dec '08

Hi, I was happy for using phenix but am struggling with a strange result on completeness calculation. One typical data set I used kept showing low completeness, so I used the same mtz, and pdb file on Refmac: it turned out has more than 98% whereas phenix.refine gave me about 46% completeness. I have slightly lower value of R but higher Rfree from phenix calculation without adding H atoms. I don't know if this is a bug or a problem on my data set (hopefully not). thanks in advance, YoungJin

Re: [phenixbb] individual anisotropic adps

Currently phenix.refine does not support refinement of individual anisotropic ADP and TLS for the same set of atoms (see my previous email). However, in phenix.refine you can refine TLS and individual anisotropic ADP for non-overlapping set of atoms. Pavel.

individual anisotropic adps
by gerwald jogl 11 Dec '08

11 Dec '08

Hi All, I was wondering if there is information/recommendations out there for the resolution required to refine individual anisotropic adps. I think the recommendation for shelx is at least 1.5 A resolution. In addition, is phenix set up and would it make sense to combine tls with individiual anisotropic adps? All comments welcome, Gerwald

Hi all, I would like to compare maps from different phasing runs, so it would make my life much easier if I could keep the same origin. I recall this could be done in solve/resolve, but can't seem to find it mentioned in the phenix documentation. Any suggestions? Thanks!

When I types "phenix.elbow --final-geometry=test10bcoot_h_refine_001.pdb --residue=ADP --output=model_h", it went on but failed with the following error message: Traceback (most recent call last): File "/home2/yjcho/phenix-1.3-final/elbow/elbow/command_line/builder.py", line 1201, in <module> run() File "/home2/yjcho/phenix-1.3-final/elbow/elbow/command_line/builder.py", line 1108, in run molecule = post_process(molecule, options) File "/home2/yjcho/phenix-1.3-final/elbow/elbow/command_line/builder.py", line 577, in post_process options, File "/home2/yjcho/phenix-1.3-final/elbow/elbow/utilities/optimisation_manager.py", line 331, in optimisation_manager pre_opt)) File "/home2/yjcho/phenix-1.3-final/elbow/elbow/chemistry/IOMixins.py", line 857, in WritePDB original_order=original_order, File "/home2/yjcho/phenix-1.3-final/elbow/elbow/chemistry/IOMixins.py", line 965, in WritePDB2String self.AdjustHydrogenNames() File "/home2/yjcho/phenix-1.3-final/elbow/elbow/chemistry/IOMixins.py", line 940, in AdjustHydrogenNames if test_name[3]==" ": test_name[3]="0" TypeError: 'str' object does not support item assignment FYI. ADP is names as ADP as a residue name in the pdb file but has different chain names. By the way, I should mention that I used phenix.reduce first for adding H atoms but it was not able to add sugar H's in ADP molecule albeit other residues were fine. Thanks in advance for your help.

phenix.autobuild- multiple models
by meindert lamers 30 Nov '08

Hi all, I am a bit puzzled by an error message I get when trying to run phenix.autobuild. (I am using the latest/final version of phenix: PHENIX VERSION: 1.3 of 11-08-2008) phenix.autobuild data=01.mtz model=3mei_coot.pdb multiple_models=True include_input_model=True \ multiple_models_number=1 n_cycle_rebuild_max=5 This gives me: **************************************** AutoBuild Input failed Sorry, multiple_models is only available with rebuild_in_place **************************************** However, when I run the same commands using an older version of phenix (PHENIX VERSION: 1.3 of 23-03-2008), all runs fine. Any ideas ? Meindert

R/Rfree from phenix.autobuild
by Graeme Winter 28 Nov '08

28 Nov '08

Hi Folks, Quick question about R/Rfree from phenix - I ran the autobuild and it kindly built pretty much all of the visible residues, and it gave me the following output: SOLUTION CYCLE R RFREE BUILT PLACED 1 1 0.22 0.23 169 169 2 2 0.21 0.23 170 170 3 4 0.22 0.23 170 170 Now, I'm not one to complain about good results, but I did feel that the Rfree looked a little close to the R factor - usually I would expect a difference of maybe 4-5%. Is there a reason for this that I am missing? The model seemed to fit very nicely, closely corresponded to the PDB entry and the waters were pretty good. There is no NCS (one copy in the ASU) and the phases are from SeMet mad data from Autosol. Resolution is ~1.6A, if that is any help. Just noticed this and thought it was interesting. I am used to Arp/wArp for automated tracing, which typically gives a bigger difference... Many thanks, Graeme

0 for wxc_scale and wxu_scale?
by Michaela Kramer, Biochemisches Inst. 27 Nov '08

27 Nov '08

I am refining a structure with a resolution of 2.1 Angstroem using Phenix. The spacegroup is P 31 2 1 (No. 152) with a twin fraction of 0.37 and twin law -h,-k,l. In the refinement procedure the NCS (4 chains) constraints are on, using individual sites, ADP and occupancy refinement. In the last refinement step, I use the option to optimize the values for wxu_scale and wxc_scale. These values are optimizes to 0 for wxc_scale and close to 0 for wxu_scale (0.2) When I tried this at earlier refinement stages wxu_scale was also here optimized in some refinement macrocycles to 0. Interestingly I obtain better R values (0.1948/0.2184), than without the optimization by using the default values (0.1391/0.2438 Rwork/Rfree). In addition to that the statistics are better: clashscore 14.41 (compared to 25.73 without wxc_scale & wxu_scale optimization), rotamer outliers 2.33% (compared o 4.66%) and Ramachandran favoured (Molprobity). How is it possible that wxu_scale and wxc_scale can be optimized to 0 by having better statistics? The total refinement target is defined as Etotal= wxc_scale x wxc x Exray + wc x Egeom As I understand it, the crystallographic refinement target (Exray) would now not be considered in the refinement procedure. Would this refinement procedure be valid? And how is wxc (output of target weights: x-ray data) defined?

trouble in phenix.refine
by Huiying Li 26 Nov '08

26 Nov '08

I was running phenix.refine in tls mode with the following command line: phenix.refine mydata.mtz mymodel.pdb strategy=tls tls_group_selection.param mylibrary.cif against a 2.1A data set, P21211 SG, a homodimer in AU, totally 10 tls groups. The following errors occured and program stopped. I do not know how to fix the problem. Traceback (most recent call last): File "/usr/local/phenix-1.3-final/phenix/phenix/command_line/refine.py", line 5, in <module> command_line.run(command_name="phenix.refine", args=sys.argv[1:]) File "/usr/local/phenix-1.3-final/phenix/phenix/refinement/command_line.py", line 68, in run log=log) .... ... .... File "/usr/local/phenix-1.3-final/mmtbx/mmtbx/monomer_library/pdb_interpretation.py", line 970, in get_lib_link atom_dicts[angle.atom_3_comp_id].get(angle.atom_id_3, None)] IndexError: list index out of range Your help is highly appreciated.
