generating xplor map of specific size
by Scott Horowitz 03 Feb '15

03 Feb '15

Hi all, Sorry for yet another map question: what I'd like to do is be able to generate xplor maps with an explicitly defined size and shape from the command line using phenix. Just choosing a buffer around a selection will result in slightly different sizes for different PDB files, which I'd like to avoid. In my comparisons, having exactly the same dimensions and centering for maps I'm calculating from multiple slightly different variants would be very helpful. Is there a way to do this? Thanks, Scott -- Scott Horowitz, Ph.D. Research Associate Howard Hughes Medical Institute University of Michigan Department of Molecular, Cellular, and Developmental Biology Bardwell lab 830 N.

serial MR / refinement
by Eike Schulz 03 Feb '15

03 Feb '15

Dear all, I am looking for a way to automate molecular replacement and refinement runs. >From ligand / fragment screening trials we have many datasets of the same protein with various resolutions (2.8 – 1.2Å). The apo-structure is known and well refined. The cell constants are fairly similar but not in all cases identical, hence I would prefer a MR run prior to the refinement. I am sure this can somehow be realized with some shell-script but maybe there is some more sophisticated way of realising this? I would also be happy for partial solutions to the problem. Best regards Eike

Question related to Phenix refinement
by Smith Lee 02 Feb '15

02 Feb '15

Dear All, Which strategy or parameter input can be used to reduce the rotamer outliers? Which strategy or parameter input can be used to reduce the bond outliers? For all the Phenix refine strategies, can you sequence it from rough refinement to fine refinement in order? I am looking forward to getting your reply. Smith

Rwork and Rfree
by Dialing Pretty 31 Jan '15

31 Jan '15

Dear All, After a Phenix refinement (for crystal 2.5A), my Rwork is about 0.19, and my Rfree is about 0.26. Is the gap between Rwork and Rfree too karge? If too large, why it is too large and how to avoid it? I am looking forward to getting your reply. Dialing

Re: [phenixbb] making coarse maps
by Terwilliger, Thomas Charles 30 Jan '15

30 Jan '15

Hi Scott, You can use the reflection file converter in the GUI to write out map coefficients with any resolution cutoff that you like. That may be the easiest. Alternatively you can take your refined model and use phenix.maps to calculate a map at any resolution that you like without further refinement. You might also consider just adjusting the sharpening on your map which will have something of the same effect as cutting the resolution. All the best, Tom T ________________________________ From: phenixbb-bounces(a)phenix-online.org [phenixbb-bounces(a)phenix-online.org] on behalf of Scott Horowitz [horowsah(a)umich.edu] Sent: Friday, January 30, 2015 6:09 AM To: PHENIX user mailing list Subject: [phenixbb] making course maps Hi all, Although I realize this sounds counterproductive, I'd really like to be able to make a map with grid spacing that is around 3 A, even though I have a ~2 A structure, and I don't want to have to cut data before refinement.

calculating map from pdb
by Scott Horowitz 29 Jan '15

29 Jan '15

Hi all, I was wondering how to quickly back-compute an electron density map from a PDB using phenix from the command line. I'm assuming it's not hard, but I can't find documentation that would lead me to it.
