Problems installing 1.10.1 on RHEL 6.3

Hi Phenix, We are trying to upgrade Phenix on our Linux box running RHEL 6.3, kernel 2.6.32-279.14.1.el6.x86_64. I have attempted to install the Centos 5 build and I get an error message during installation: Configuring Phenix components...

Nvidia Quadro M4000 for Coot 3D?
by Xiao Lei 01 Feb '16

01 Feb '16

Hi All, As I read the Coot 3D setting guide online, it says for Linux environment I have to have at least a Nvidia Quadro card with 3 pin min DIN stereo connector and DVI connector, and the cheapest is Nvidia Quadro K4200. I plan to buy Dell workstations for Coot 3D, but they do not have the option of Quadro K4200, instead, they suggests an updated version called Quadro M4000. As I look at the product picture of Quadro M4000, I can see all connectors are DPs (displayport), not DVI connector. What is more, the Quadro M4000 does not have any connector for 3 pin mini DIN. Is the Quadro M4000 card still suitable for Coot 3D in Linux? Do I have to manually add a 3 Pin Mini DIN Bracket Stereo Connector to the Quadro M4000 card (which can be found at B&H photos) and get a Displayport to DVI connectors before it works? In addition, I found it was very hard to find a new build-in IR emitter 3D monitor from Asus or Acer, so I am looking for a Asus 3D monitor with Nvidia 3D vision 2 kits, some pictures of the 3D vision 2 kit only shows USB cable as connectors, I wonder if the kit also contains a 3-pin min din cable for the 3D? I'd appreciate if any input on this.

ACA 2016 SAS Workshop
by Kushol Gupta 01 Feb '16

01 Feb '16

On behalf of the organizing committee, I am pleased to announce a workshop on "Computational Approaches to the Structural Modelling of Biological Macromolecules using Small Angle Scattering." This workshop will take place on Friday, July 22nd, 2016 at this year's American Crystallographic Association (ACA) Meeting in Denver, Colorado, U.S.A. The meeting itself will run from July 22-26. WK.02 Computational Approaches to the Structural Modelling of Biological Macromolecules using Small-Angle Scattering. This one-day workshop will focus on computational approaches to structural modelling and analysis. In the first session, a brief reprise of fundamental concepts will be provided, with a focus on pitfalls in data acquisition and reduction that can affect subsequent data analysis and modelling. The remainder of the day will be allocated to the hand-on application of the leading software packages to the analysis of solution scatter. This workshop will feature direct participation from the creators of the most prevalent software packages currently used (including BIOSAXS(EMBL), SIBYLS, CCP-SAS, FoXs and IMP). The participating groups will present their software, including the basis for the algorithms employed, and further deliver guided hands-on tutorials for workshop participants. This approach will introduce and train participants on the appropriate application of these tools, including experimental design, model preparation, comparison of structural models using both SAS and complementary information, validation, and most importantly the limitations of interpretation with regards to the biological conclusions that can be made. The workshop format will include lectures, and a selection of hands-on practical exercises. Students will be expected to bring laptops with appropriate pre-installed software as necessary. Prior to the workshop, a website will be made available containing installation instructions and software for each tutorial. Tentative Program Schedule Basic Theory and Methods Joint Session 8:00 am - 9:30am - Introduction: what is SAS data good for? (short) - Theory Essentials: How to get your scattering profiles - SAXS and SANS: common pitfalls, how to ensure the data is suitable for modelling - Cross Checks and Validation 9:30 AM - 10:00 AM Coffee Break Software Application and Tutorial Session 10 am - 7pm 10:00 AM - 11:30 AM BIOSAXS(EMBL) lectures and guided tutorial 11:30 AM - 12:30 PM Lunch and Discussions (vendor presentations in the form of 'lunch and learn') 12:30 PM - 2:00 PM IMP Lectures and Guided Tutorial 2:30 PM - 3:00 PM Coffee Break 3:00 PM - 4:30 PM SIBYLS lectures and guided tutorial 4:30 PM - 6:00 PM CCP-SAS lectures and guided tutorial 6:00 PM - 7:00 PM Discussion Pre-registration is mandatory.

Additional conformations and partially occupied waters
by Helena Taberman 30 Jan '16

30 Jan '16

Hi, I’m trying to refine a structure determined to 1.6 Å resolution. There’s several residues with additional conformations and waters with partial occupancies stating that they would be there when the conformation of the residues allows it. When I try to refine these conformations and partially occupied waters together the refinement kicks the second conformations and water molecules out of their densities, since they are obviously too close to the other additional conformations of the residues or the following residues. What could I do? Should I somehow group them together or what? Best regards, Helena Helena Taberman, Ph.D. University of Eastern Finland Department of Chemistry Joensuu Campus P.O.

Phenix Refine Place Elemental Ions
by Xiao Lei 30 Jan '16

30 Jan '16

Hi Phenixbb members, I have a dataset of 2.7A resolution and solved by molecular replacement. Now I am refining my structure using Phenix Refine (Fedora; Version 1.10.1). I'd like to try "place elemental ions" option in the GUI. I read the Phenix refine manual and it says: " to enable this option, simply enter a list of the elements to search for; this will also enable solvent picking as a first step. This option is not recommended if you have data worse than 3.0A resolution, and works best with anomalous data." I have questions about this: 1. In my crystallization condition I have 80 mM CaCl2 and 5mM MgCl2. How should I enter the ions to search for into the GUI? Should I enter "Ca; Mg" or "Ca and Mg" or "Calcium and Magnesium" ? I wonder how the Phenix Refine can really differentiate Ca or Mg in the map. 2. Phenix Refine says the place elemental ion option works best with anomalous data, does the anomalous completeness needs to be over 80% to consider anomalous data? Tough I did not do MIR or Selenium which produces anomalous signals for phase, Phenix Xtriage shows my data has anomalous completeness around 70% (I even do not know what caused the anomalous signal in my dataset). Does this help Phenix Refine to locate elemental ions? Thanks ahead.
