phenix.maps: a command line tool to compute various maps
by Pavel Afonine 04 Feb '10

04 Feb '10

Starting PHENIX nightly build version 1.6-295 (or whatever next version), the new command line tool phenix.maps is available. As the name suggests, this is the tool for map calculation: regular (p*Fobs-q*Fcalc) or maximum-likelihood (p*mFobs-q*DFcalc), with any user-defined coefficients p and q, as many as requested. For example, 2mFo-DFc, 3Fo-2Fc, mFo-DFc, Fc, Fo, Anomalous difference maps can be all computed at once. Also, a user has a full control over various map calculation parameters, such as filling missing Fobs with DFc, computing kick maps, etc. Maps can be output in X-plor formatted files or as Fourier map coefficients in MTZ formatted file. X-plor formatted maps can be computed for the whole molecule/unit cell or any selected part of the structure. This new tool is meant to be a replacement for current practice of computing the maps using phenix.refine (although, phenix.refine still output maps as before). For more information and usage examples simply run phenix.maps . This is available from PHENIX GUI too (thanks Nathaniel Echols). For usage instructions and quick manual type phenix.maps and hit Enter. Please let me know should any questions or problems related to using this tool arise. Pavel. P.S. Below is the result of running phenix.maps: phenix.maps: a command line tool to compute various maps. How to run: 1. Run phenix.maps without any arguments: just type phenix.maps in the command line and hit Enter. This will create a parameter file called maps.params, which can be renamed if desired. 2. Edit maps.params file to specify input/output files and the desired maps. It is possible to request as many maps as desired. 3. Run this command to compute requested maps: phenix.maps maps.params Remarks: - The scope of parameters 'map_coefficients' defines the map that will be output as Fourier map coefficients. The scope of parameters 'map' defines the map that will be output as X-plor formatted map. - To create several maps: duplicate either 'map_coefficients' or 'map' or both scopes of parameters as many times as many maps is desired. Then edit each of them to define the maps. - A map is defined by specifying a map type using 'map_type' keyword available within each scope of parameters: 'map_coefficients' or 'map'. The general supported format for 'map_type' is: [p][m]Fo+[q][D]Fc[kick][filled]. For example: 2Fo-Fc, 2mFobs-DFcalc, 3Fobs-2Fmodel, Fo-Fc, mfobs-Dfcalc, anom. The 'map_type' parser will automatically recognize which map is requested. - The program creates as many files with X-plor formatted maps as many X-plor formatted maps is requested, and it creates only one MTZ formatted file with all Fourier map coefficients in it. - The X-plor formatted map can be computed in the entire unit cell or around selected atoms only. - Kick maps and missing Fobs filling is done (if requested) as described in Adams et al. (2010). Acta Cryst. D66, 213-221. - Twinning (if detected) will be accounted for automatically. - All arrays used in map calculation, for example: Fobs, Fmodel, Fcalc, Fmask, m, D, etc., can be output into a CNS or MTZ formatted reflection file.

Completeness issue by phenix - revisited
by J. Fleming 03 Feb '10

03 Feb '10

Hi, I'm having a problem using phenix.refine with my x-ray data. My completeness is always 89% when it should be 99%. My data was originally processed with CCP4i. I found an old post (see below) with a potential fix that doesn't work for me. I've tried changing the 'Anomalous flag: True' to 'Anomalous flag: False' but my completeness is still 89%. I've clicked through a variety of other setting in the GUI that I thought would help but no luck. Does anyone have any ideas? Thanks in advance, Jon ----- Original Message ----- From: "Ralf W. Grosse-Kunstleve" <rwgk at cci.lbl.gov <http://www.phenix-online.org/mailman/listinfo/phenixbb>> To: phenixbb at phenix-online.org <http://www.phenix-online.org/mailman/listinfo/phenixbb> Sent: Monday, December 15, 2008 12:59:12 PM GMT -05:00 US/Canada Eastern Subject: Re: [phenixbb] Completeness issue by phenix Hi YoungJin, I suspect phenix.refine decided your mtz file contains anomalous data when you actually have non-anomalous data. Could you look in the phenix.refine output for something like this: ================================== X-ray data ================================= F-obs: 1yjp.mtz:FOBS_X,SIGFOBS_X R-free flags: 1yjp.mtz:R-free-flags Miller array info: 1yjp.mtz:FOBS_X,SIGFOBS_X Observation type: xray.amplitude Type of data: double, size=495 Type of sigmas: double, size=495 Number of Miller indices: 495 Anomalous flag: False ^^^^^ in particular here If you see "Anomalous flag: True" try adding this to the phenix.refine command line: xray_data.force_anomalous_flag_to_be_equal_to=False Let me know if this doesn't help. If it does help, I'd be interested to know how the .mtz file was generated. Ralf

AUTOSOL for MAD data with error message-'Need a symfile for solve'
by m.b.rajasekaran＠reading.ac.uk 02 Feb '10

02 Feb '10

Dear all, I have a query regarding the Autosol option in the PHENIX-1.6-289 version. We are trying to process a MAD data for a zinc bound protein crystal with AuTOSOL. We uploaded the scaled files, sequence and all other details and started running AUTOSOL. But the program stopped with the following error message pasted below mentioning some missing of symfile. We were not able to locate any parameters file on the installation directory. It would be helpful if we get some useful suggestions on this.

automatically changed refinement parameters
by Sara Züger 02 Feb '10

02 Feb '10

Dear phenixbb, I have some questions regarding refinement parameters: When I run phenix v1.6 via the GUI, starting a fresh refinement session from the main window (I do TLS+isotropic ADP refinement and 5 macrocycles, otherwise everything default), I saw these non-default refinement settings in the run, which I did not specify myself, but the program: adp_restraints { iso { use_u_local_only = True sphere_radius = 1.55 distance_power = 0 average_power = 0 }} In the documentation I found that when doing TLS+isotropic ADP refinement, only Ulocal is restrained, so the first command makes sense. But how is it with the sphere_radius, distance_power and average_power? The default parameters are sphere_radius= 5.0 distance_power= 1.69 average_power= 1.03 What do these parameters mean? What does it mean when these parameters have changed (and why did they change)? And is it ok at all that they changed? And would they have an influence if I modify the start model by setting b_iso to a certain value and then refine "normally" with TLS+isotropic? Another parameter that changed and I did not specify is: Target_weights { wxu_scale = 2.72 } Why did this happen, is it because few cycles before I included optimize_weights? And why would this change the weights permanently? Does it make sense? Thank you for explaining me these things! Sara

Dear Mohan, I'm sorry for the trouble! I have not seen this one, but it must be a bug that I need to fix. Can you possibly send me the data file and exact command used (you can just send data to low-res such as 6 A if you like) and I will fix it? In the meantime...if you split your dataset up into individual files I would expect that to work, particularly if you convert to .sca.

data used in refinement
by Karolina Michalska 01 Feb '10

01 Feb '10

Hi all, I have a question concerning number of reflections used in refinement. In the phenix.refine log I can find a table saying that there are 34314 reflections in a work set and 1104 in a free set. This is in agreement with what Refmac prints out to pdb file under REMARK 3 (DATA USED IN REFINEMENT). However, the same remark in the pdb file produced by phenix.refine says there are 35404, which is neither a work set nor a sum of work and test sets. It is almost the latter option but still 14 reflections are missing and I cannot find in the log file what happened with them. Can anyone help me here? Karolina
