Re: [phenixbb] cci_apps on irix
by o.h.weiergraeber＠fz-juelich.de 22 Aug '08

22 Aug '08

Hello Nat, thanks for your suggestions. Yes, I have used these tricks before, but sadly, the cci_apps build system ignores them completely. As far as I can see, there is no "central" place to set these variables, and the component packages behave differently. The cleanest way to go would be to just correct the syntax problems. Until recently, cci_apps was available as a precompiled irix package (and I think it was mipspro), so maybe one of the developers could comment on the specifics of this compilation.

phenix.pdbtools

Hi, I am trying to use phenix.pdbtools to calculate the geometry statistics for a model from Rosetta. "phenix.pdbtools --show-geometry- statistics foo.pdb" stopped with a message "Sorry: Number of bonds with excessive lengths: 707". Anybody know what happened there? Thanks. -- Jianghai

placing ligands in coot with phenix.elbow output
by Feldman III, George Franklin 20 Aug '08

20 Aug '08

Hi all, I am having difficulties with my ligand. My ligand is an FMN (flavin mononucleotide) and its pdb file was originally created using PRODRG. I used the DRGFIN.PDB output file to run elbow (phenix.elbow DRGFIN.PDB --opt). The output contains hydrogens, which as we all know do not work well with coot. So when I try to place my ligand in its correct position and save the coordinates in coot, I get an error of duplicated atom labels when trying to merge the molecule to the ligand using phenix.refine. I tried using the command "phenix.elbow DRGFIN.PDB --opt --write-hydrogens=False" but phenix told me that last command doesnt exist (although its posted on the web page). Manually changing the atom names will affect both the connectivity and the cif file (I think), so it is an option I would rather avoid. Is there a way around all of this? Best Regards, George (Trey) Feldman

Re: [phenixbb] [phenix] generate r free flags in phenix.refine not obeying high resolution limit?
by Pascal EGEA 20 Aug '08

20 Aug '08

Hi All, Following Pavel's answer to Francis Reyes, I have a very basic question about this too. What is a good distribution of reflections and what are thin bins of resolution to ensure correct ML estimations? Are there any basic statistical rules that should be considered. Thanks Pascal Pascal F. Egea, PhD Post Doctoral Researcher University of California San Francisco Department of Biophysics and Biochemistry Robert Stroud Laboratory pascal(a)msg.ucsf.edu

generate r free flags in phenix.refine not obeying high resolution limit?
by Francis E Reyes 20 Aug '08

20 Aug '08

Hi all When generating R-Free flags from phenix refine, flags are generated all the way to the limit of the data. However, shouldn't flags be generated up to the limit of the data if specified via refinement.input.xray_data.high_resolutio n ? If not, are the statistics for R/Rfree matching to high resolution data that may be suspicious ?

Hi all, A quick question about extracting info/preparing pdb file for deposition.......... I've got a pdb file after refinement using phenix 1.3b. I was wondering if there is a way to prepare this file / format this the same way as in 1.3 final where we get "REMARK IF THIS FILE IS FOR PDB DEPOSITION: REMOVE ALL FROM THIS LINE UP" and REMARK 3. i'm already running refinement 1.3 final with the same parameters just to quickly compare the resulting refined files/numbers. I guess I could do it manually but curious if there is an easier way using 1.3 final. thanks, Sid.

Resolution cutoffs. Always debated?
by Francis E Reyes 20 Aug '08

20 Aug '08

I need to put this in front of (this) crystallographic community. What are the criteria for cutting a resolution for data reduction ? Rmerge, I/sig, mean I/sig, completeness... more? I once believed that I/Sig (not averaged) greater than 2 was the cutoff, but I've read online (particularly http://www.mail-archive.com/[email protected]/msg02576.html) that this is no longer the case because of maximum likelihood. I would love to know why this is the case as well as poll the community on how they cut off their data.
