Hi Nick, I think I tried that at some point, but the problem lies in the IOBS. Some are regular float fortran format: INDE 3 0 0 FOBS= 100.142 SIGMA= 1.478 IOBS= 10028.400 SIGI= 293.800 TEST= 0 while other IOBS are large and for some reason CNS decided to put them in scientific notation such as INDE 5 0 0 FOBS= 492.449 SIGMA= 17.677 IOBS= 0.242506E+06 SIGI= 17098.000 TEST= 0 As far as I can tell this requires two sets of fortran format statements for f2mtz to work properly. format '(6X,3F5.0,6X,F10.3,7X,F10.3,6X,E15.3,/,24X,F10.3,6X,F10.0)' or format '(6X,3F5.0,6X,F10.3,7X,F10.3,6X,F10.3,/,24X,F10.3,6X,F10.0)' I'm playing around with with grep to separate the original cv file into reflections with IOBS in F10.3 format and those with IOBS in E15.3 format, convert with f2mtz, then CAD them together, but this is bloody cumbersome. I was hoping phenix.refine would just automagically figure it all out.

Hi, how can one enter f_prime and f_double_prime values for SIRAS/MIRAS experiments in phenix.autosol? Could not find any examples of that in manual, only for MAD. Just putting them in as f_prime=... and f_double_prime=... does not work, it then assumes MAD experiment. Thanks! -- Dr. Leonid A.

Deadline for ALS PX beamtime this Thursday, Jan 15.
by Peter Zwart 12 Jan '09

12 Jan '09

Dear All, The deadline for general user proposals for PX beamtime at the ALS is coming up soon (Jan 15)! At the BCSB, we have 5 beamlines for which you can apply for beamtime. At the Berkeley Center for Structural Biology (BCSB) we have recently completed a number of upgrades: Sector 8: Recent improvements include: * A high-accuracy microdiffractometer on BL 8.2.1, allowing for centering and viewing of very small crystals * Robotic automounters which can increase the screening throughput at the beamlines, and allows for the implementation of remote data collection. * A new large format (315mm active surface area) CCD detector on BL 8.2.1, facilitating data collection on large unit cell crystals Sector 5: Beamlines (5.0.1 and 5.0.3) now generate 1.5x10^11 photons per second at 0.97 Angstrom. This wavelength is slightly above the Se K edge making them ideal for performing Se SAD experiments. Beamline 5.0.2 (the tunable beamline) generates a peak flux of 8x10^11 photons per second, and the energy range of 5.0.2 has been extended to 17 keV, enabling the routine use of shorter wavelengths and anomalously scattering elements such as bromine. Remote data collection for general users on sector 5 is currently being tested for a limited number of users. Please contact beamline staff for details. Please visit http://bcsb.lbl.gov/ for more details about the Center and its beamlines. If you'd like to apply for next round of beamtime (March-April) at the Advanced Light Source, please submit a General User proposal by Januari 15, 2009. To find out more, click on: http://www-als.lbl.gov/als/quickguide/independinvest.html We invite you to submit a proposal at: http://alsusweb.lbl.gov/4DCGI/WEB_GetForm/PXProposalEntry.shtml/Initialize If you have any questions or would like to request open beamtime, please e-mail BCSBBeamtime(a)lbl.gov. (Please note that executed user agreements must be received by LBNL prior to beamtime. Proprietary fees, if applicable, must be received by LBNL at least five working days prior to scheduled beamtime.) ----------------------------------------------------------------- P.H.

Hi Miles, > Thanks for the info. I see where I can load a parameter file in the > gui (File => Open parameter file) but I don't think I have it with the > right extension (.eff or .param). I'll give it a whirl tomorrow. Oh good, I'm glad to hear that this exists! I'm not sure if it relies on the file extension (it wouldn't be right if it does). I think we should have this option (to load a parameters file) right next to the prompt for PDB, data and CIF files. Best, Pavel.

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

09 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 06 Jan '09

06 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

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

Dear all The GUI of phenix installed in Fedora 8 takes longer time, sometimes 30mins. Can anyone help in this regard, what is the problem and how it can be sorted out? Thanx in advance Shivesh

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.
