changing mtz from P 31 2 1 to P 32 2 1
by Sebastiano Pasqualato 16 Feb '17

16 Feb '17

Hi guys, is there an utility in phenix to change hand of an mtz file? I’m interested in getting a P 32 2 1 mtz from a P 31 2 1. phenix.refine does handle the refinement in P 32 2 1 even with the P 31 2 1 mtz, but the polder map calculating tools complains about discrepancy between the pdb and the mtz. Thanks in advance, ciao, S -- Sebastiano Pasqualato, PhD Crystallography Unit Department of Experimental Oncology European Institute of Oncology IFOM-IEO Campus via Adamello, 16 20139 - Milano Italy tel +39 02 9437 5167 fax +39 02 9437 5990 web http://is.gd/IEOXtalUnit <http://is.gd/IEOXtalUnit>

by Terwilliger, Thomas Charles 10 Feb '17

10 Feb '17

Colleagues, Like many of you, we are concerned over the recent upheaval surrounding travel to and from the United States.The ACA is committed to hosting an annual meeting that brings together a diverse community of scientists, no matter what their country of origin. Our mission includes diversity and a desire to foster a global community of structural scientists, in accordance with the principles of the International Union of Crystallography. While we understand any reluctance to travel to the US at this time, we would like to encourage anyone who is interested in attending the meeting in New Orleans this May to register now and to submit an abstract should you wish to present your work. We will offer a full refund of registration costs to anyone who is denied entry into the US or cannot risk the travel because of travel restrictions. We want you to know that all scientists are welcome at the ACA. Sincerely, The Members of the ACA Council Amy Sarjeant, President Tom Terwilliger, Past President Lisa Keefe, Vice President Sue Byram, Treasurer Diana Tomchick, Secretary Tomislav Friscic, Canadian Representative Hanna Dabkowska, IUCr Representative Bill Duax, CEO Marcia Colquhoun, Director of Admin.

solvent masks
by Kajander, Tommi A 10 Feb '17

10 Feb '17

Hi All, Was there a convenient way to make a solvent mask for a region with a model - its been a while - and use that to generate maps (i have a domain that is only partially visible, could not be found be molecular replacement), its there though. Could be that its not well ordered, but I was wondering if the bulk solvent masking is just wiping it out. (basicly something like half a domain, e.g. half of individual beta-strands, are missing.) resolution is bit limited (at best 3 Å) so automated building and refinement doesnt work terribly well. I could just place a model there and make a mask somewhere and include in map calculation? Thanks for suggestions, tommi

phenix.composite_omit_map
by Dyda 09 Feb '17

09 Feb '17

Dear Phenix BB, I have a moderate resolution structure that I refined using secondary structure restraints (both for nucleic acid and for protein) I'd like to use phenix.composite_omit_map to calculate such a map. Is it possible (and if so how) to make phenix.composite_omit_map to use the same restraints during annealing of the not omitted parts? Thanks!

Re: [phenixbb] Running Phenix Gui on Debian 8
by Chow, Martin 08 Feb '17

08 Feb '17

I am having troubling running Phenix 1.11.1.2575 gui under Debian 8 (Jessie), and have same results with different computers that are running the same system. I have no problem with previous versions like 1.9 and 1.10. However, with 1.11, Phenix guy won’t run. It complains about Gtk+ or Glib etc and quits. I know these are related to gui tool kits. I have tried Centro5, Centro6, and even compiled it, they all give similar or same complaints. I believe command-line works, but never try. However, simple commands like —version or —-help etc work. I just tried it on Red Hat, 1.11 works without issues. Clearly, it is a problem with the Linux Distro. Thank you.

pdbtools atom_selection behavior
by wtempel 07 Feb '17

07 Feb '17

Hello all, suppose I would like to remove one alternate conformation B from residue 1 in chain A and set the occupancy of remaining atoms in that residue to 1. phenix.pdbtools alts_minim.pdb occupancies.set=1 \ occupancies.atom_selection=”chain A and resid 1” \ keep=”not (chain A and altid B and resid 1)” \ output.file_name=alts.out.pdb There are better methods to achieve that, but I eventually would like to expand this command to do other “things” to my coordinates. Well, so far I have failed to have the atom_selection to work the way *I* expect. stdout reveals that the program fails to apply a common scope to the command switches, and proceeds to reset occupancies of all atoms. Can this be done on the command line? A minimal (not) working example is attached, and your feedback appreciated. Best regards. Wolfram Tempel

Scale and merge multiple data sets
by Sam Tang 05 Feb '17

05 Feb '17

Dear colleagues Hello again. I would like to scale and merge two different native datasets for a same protein complex (which semed to die off gradually in the beam) using the scale_and_merge tool. The error message was received "Multiple intensity arrays - please specify one: data_labels=I,SIGI data_labels=IPR,SIGPR" However I looked into the log file and I have actually included "data_labels = "IPR,SIGIPR,merged" . Perhaps I have missed something else in the setting? Regards Sam Sam Tang Biochemistry Programme, School of Life Sciences, CUHK
