extracting PHENIX structures
by Patrick 24 Jan '15

24 Jan '15

Hi, not directly related but I wanted to know how to extract from the PDB all the PHENIX/CCP4 refined structures currently deposited. Do I use the "text" search in quarry to get the result or do I use the software? I tried it for both but seems to give different results (no's). I tried for another refinement package (shelx) and same, different no's Using software, and looking for contains 320 using text search 130 Is there another way to get structure of a certain resolution ?

Problem during refinement
by Almudena Ponce Salvatierra 24 Jan '15

24 Jan '15

Dear all, I have partially rebuilt my model after autosol and now I would like to submit it for refinement to Phenix refine. However when I do so, even though the R factors go down when I have a look at the result, it just looks awful! All the model is placed out of the electron density map, plus the electron density map doesn't look anymore like a 3 A one, but just like sausages. Why is this happening? The truth is I have no idea... What I do is to provide Phenix refine with overall_best_refine_data.mtz (coming from autosol) as phases, x Ray data and x Ray r free data. Additionally, the starting model and the sequence. Any suggestions are more than welcome. Thanks a lot in advance. Best wishes, Almudena -- Almudena Ponce-Salvatierra Macromolecular crystallography and Nucleic acid chemistry Max Planck Institute for Biophysical Chemistry Am Fassberg 11 37077 Göttingen Germany

resolve phases/fom
by "Weiergräber, Oliver H." 24 Jan '15

24 Jan '15

Hello, while compiling phasing stats for a manuscript, I came around the following question: Having run autosol (on a SAD dataset) from the command line, where to find the latest density-modified phases (with associated FOMs) _before_ the onset of model building? The PHIM and FOMM columns in the denmod_i.mtz files are obvious candidates - just want to be sure since this particular FOM does not seem to be echoed in the log files, as far as I can see.

Reflection file editor. copying Free set from one to other mtz.
by Tarek DawoD 23 Jan '15

23 Jan '15

Unfortunately i did not find a detailed explanation for how to use reflection file editor (GUI) i just want to know if i am right and i have a questions about how it works as well 1- if i have 2 myfile-data.mtz files (for the same structure but 2 different ligands, one of them 1.9 A and the other 1.6 A) and i want to copy free set from one to the other. so i have in the (ALL Input Arrays) 2 intensity and 2 R-free flag. so what i did is to add in the (output array) one of the intensity which belongs to one and one R flag which belong to other. i was not sure how to use the other output options??? what should i check or uncheck in this particular case??? 2- How this works? suppose i have h k l (6 7 21) has flag 1 in the data.mtz file (the one i used to copy the free set to other mtz), if i will copy this to other mtz (which has no R flag of course), the program will look for (6 7 21) h k l in the other mtz to give it also flag 1. Am i right.??? 3- if i am right in number 2, Suppose the other mtz has no (6 7 21) h k l what will happen? if it is just ignoring it or assign flag 1 for other h k l which did not exist in the first data.mtz.this means it is impossible to get 100% free set similar between say the 2 mtz files in this case. thank you in advance thank you Dr Pavel and Dr Georg for your reply to my previous query TK DawoD

Solving installation problems on network volumes in Yosemite
by Chris Richardson 23 Jan '15

23 Jan '15

I thought I’d post this in case anyone has a similar problem in the future. It’s taken me a couple of days of frustration to find the solution; maybe I can save someone else some pain. This problem only occurs when trying to install Phenix on an NFS-mounted volume in OS X 10.x, Yosemite. If this doesn’t apply to you (and I might be the only person doing this), you can happily ignore what follows. The problem: In an effort to save us from malware, OS X now adds a ‘quarantine’ attribute to downloaded files. This includes tar and compressed tar files. For most users the quarantine flag only really comes into play if the downloaded file is an application or installer package. When Yosemite untars an archive with the quarantine attribute, it adds the quarantine attribute to every file it extracts from the archive. This doesn’t present a problem if you’re extracting the archive to a local disk, or an AFP-mounted network volume. If you’re extracting the archive to an NFS-mounted network volume, it can’t store the quarantine flag as a resource fork on the file itself. Instead, it creates a ._<filename> file for each extracted file. The Phenix installer doesn’t like having an install tree full of unexpected ._ files. In some cases, such as where generate_henke_cpp.py tries to generate tables from all the files in a directory, it tries to read ._ files as normal files and dies. The solution: The solution is trivial once you know what the problem is. Remove the quarantine attribute from the tar file before extracting its contents. For example: xattr -d com.apple.quarantine phenix-installer-1.9-1692-mac-intel-osx-x86_64.tar.gz Of course, if the Phenix installer could be modified so that it doesn’t die when it finds unexpected ._ files, that would be lovely.

Rfree % calculation
by Tarek DawoD 22 Jan '15

22 Jan '15

Dear ALL when you start you refinment in phenix with ***.sca file, fraction of reflection in test set will be created. under options (bottom) in phenix refine, you could see that fraction of reflection in test set is 0.1 which means 10 %by looking to the PDB header for completely different structures (below) you will find different percentage but always FREE R VALUE TEST SET COUNT is around 3800. so it always take the same 3800 count regardless the number of reflections. when you look in generated mtz file after the refinment, you see under R-free-flags(+) and R-free-flags(-) either 0 or 1. what does 0 or 1 mean? thank you in advance for explaination.

Problems installing Rosetta
by 신인철 20 Jan '15

20 Jan '15

Hi, I am trying to install rosetta on Fedora 21. I downloaded rosetta_bin_linux_2015.02.57538_bundle.tgz and copied the unpacked whole directory under /usr/local/ and rename "rosetta_bin_linux_2015.02.57538" as "rosetta" simply.

Bug in phenix.carbo_load in latest nightlies
