phenix.phaser params.eff output directory
by G Y 26 Jul '11

26 Jul '11

Dear all, I am writing a script for phenix.phaser. The keyword "output_dir" seems not work. In params.eff file I give it a line like: solution = None output_dir = /home/.../somedir/ keywords { general { root = "PHASER" title = "[no title set]" verbose = None debug = None mute = None xyzout = ON hklout = ON jobs = 2 } But I can not generate output file in the specified directory(somedir in the above case). The output files are always put in current working directory. Did I choose a wrong keyword to do this? What would be the correct way? Any answer would be appreciate greatly. Many thanks. regards, GP

mr_rosetta with fixed solutions for other chains
by Bard, Joel 25 Jul '11

25 Jul '11

Hi- We have data for a crystal where two of three components have high homology search models and can be found with straightforward phaser runs but the third component has much weaker homology to anything in the pdb. Is there a way to provide the solution for the first two components and let mr_rosetta work on the third? Thanks, Joel

cif file for internal bond with one of two alternative conformations
by Daqi Tu 25 Jul '11

25 Jul '11

Hi, I have a structure of drug bound to a protein. The drug has two alternative conformations, in which one of them has an internal bond making it a cyclic compound. How do I refine a structure like this? What modification should I do to its cif file, which I generated using elbow without the internal bond. Thank you. Daqi Tu (sorry if I have double posted.)

phenix.phaser params.eff labin problem
by G P 25 Jul '11

25 Jul '11

Dear all, I am now writing a script for phenix.phaser. In the input file params.eff there is a keyword labin which corresponds to the labels inside input mtz files. The important columns in my ccp4 mtz file are FP, SIGFP. I edit the line of labin as: labin F=FP SIGF=SIGFP when running the script, it returns me: Syntax error: expected "=", found "F" (file "params.eff", line 9) So, I changed it like: labin=FP SIGFP when running, it gave me the message: Sorry: Couldn't find array FP SIGP in file I also tried: labin="FP" or labin = "FP SIGFP" or labin="labin F=FP" and so on. With nothing it can find the right columns. My mtz file should be not problem, I checked with mtzdmp, the columns FP and SIGFP were there and with phenix GUI this file works well. Would someone know exactly how to edit this line in params.eff? Many thanks! GP

Alternate conformer and HOH clashes
by Yuri 24 Jul '11

24 Jul '11

Thanks guys... What about waters, do they follow the same ALTLOC rules? I have a high res data 1A and I see lots of things... Ill probably bother you again with some questions as I keep refining. Best, Yuri -- Yuri Pompeu

Alternate conformer and HOH clashes
by Yuri 24 Jul '11

24 Jul '11

Dear All, I am having trouble refining multiple conformers that would clash into a neighbouring side chain that also has an alternate conformer. An attempt to clarify: Lets say a Tyr residue has conformation A1, but also moves into a position B1. In postition B, its side chain would clash into a neighbour Phe A2. However this Phe has another conformation B2. Bottom line, B1 and B2 would not clash, neither would A1 and A2. Any other combo (A1 B2, etc...) would clash. When I model it all in I see problems... I encounter the same situation with partially occupied HOHs. Whats the best way to deal with this Thank you -- Yuri Pompeu
