how can I merge denzo output files
by lbetts0508 . 10 Jan '15

10 Jan '15

I hope I am a dummy and I missed the obvious, but if I have a list of ".x" files from DENZO integration and want to merge and scale them as an mtz file in phenix or xds (I don't have access to scalepack) is there a pre-written program for that? Laurie Betts

a question related to Phenix and Coot
by Dialing Pretty 10 Jan '15

Dear All, When I use WinCoot 0.8.1 to open a PDB file got by Phenix.refine, it comes, Fix Nomenclature Errors. Correct them? Asp [spec: 1 "A" 128 ""]PHE[spec: 1 "A" 134""]PHE [spec: 1 "A" 371""] But when I check the 3 residues, I cannot find any error. Will you let me know the issue? Dialing

A question related to Phaser-MR (simple interface)

Dear All, When I run Phaser-MR, I met a fatal error "The composition you have entered has a protein/nucleic acidcontent of 132.513%, which is impossible. DECREASE your composition". Can you remind me in which black I fill the composition? And how to decrease it? Dialing

advice on 'Fit rotatable H or D' refinement stage in phenix.refine
by Anna Makal 07 Jan '15

07 Jan '15

Hi, I would like to ask for advice concerning 'Fit rotatable H or D' refinement stage in phenix.refine. I am attempting to run unconstrained refinement on a certain high-resolution protein dataset: just XYZ and ADPs refinement for every single atom in the structure, with hydrogen atoms treated with individual approach. It turns out that when I set more then 3 macrocycles, the 'Fit rotatable H or D' refinement stage is activated in every macrocycle prior to 'XYZ individual' refinement stage. I am using version 1.9, release 1692 for windows. When I last worked with PHENIX, it was distribution 1342, and I am positive I have not come across such refinement stage. It seems that TARDY is involved at that stage. As I specifically do not want to introduce any kind of torsion angle dynamics in my current refinement, I would like to ask, what command/option shall I use to deactivate this stage of H-atom fitting in my refinement? With regards, Anna Makal

Coot failed to launch in Phenix after CCP4 update
by Shun Liu 07 Jan '15

07 Jan '15

Dear all, After I updated ccp4 to a new version (ccp4-6.5), I found that coot failed to launch in phenix. /Applications/PHENIX-1.9-1692/Contents/phenix-1.9-1692/build/mac-intel-osx-x86_64/../../phenix/phenix/command_line/start_coot.sh: line 37: /Applications/ccp4-6.4.0/coot.app/Contents/MacOS/coot: No such file or directory Apparently it requires ccp4-6.4.0, which has been deleted. I tried to modify find_coot_command.py in phenix, but it didn’t work. Can anybody give me some suggestions so that I can figure this problem out? Thanks! Best, Shun

FEM maps
by Colin Levy 05 Jan '15

05 Jan '15

Dear All, when using FEM maps I notice that some solvent structure has clean (ish) 2Fo-Fc but not FEM density. Is this indicative of the water without FEM density being simply noise or is it more complicated than that? Many thanks, Colin Manchester Protein Structure Facility Dr. Colin W. Levy MIB G034 Tel. 0161 275 5090 Mob.07786 197 554 c.levy(a)manchester.ac.uk<mailto:[email protected]>

phenix.refine reference?
by Ulrich Baumann 04 Jan '15

04 Jan '15

Dear colleagues, a very happy New Year 2015 to all of you! Is there a specific reference for phenix.refine, please? Or is it ok if we cite Adams et al., Acta Cryst D66, 213-221 (2010) or the 2011 paper on Phenix? What about Xtriage? Thanks you very much for your kind help! Best wishes, Ulrich

a command on Phenix refine
by Wind Sui 04 Jan '15

Dear All, I use the graphic phenix.refine to do a refinement, and Phenix informed me I need to have a command "refinement.pdb_interpretation.clash_guard.nonbonded_distance_threshold=None". Will you please tell me by graphic phenic.refine, how can I input this command? Wind
