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

Re: [phenixbb] AUTOSOL for MAD data with error message-'Need a symfile for solve'

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

auto-open MTZ scheme
by Paul Emsley 29 Jan '10

29 Jan '10

Dear Phenixers, Prompted by Randy Read, Kevin and I have agreed that Coot should be able to auto-open MTZ files with columns labelled groupname.F_phi.F and groupname.F_phi.phi and groupname.DF_phi.DF, groupname.DF_phi.phi for difference maps for any value of groupname, of course. (Any weights should be applied to Fs before writing the file). We were wondering what the Phenix community/developers thought about that idea (there's not much point in adding this feature if you don't agree). Thanks, Paul.

For your consideration: Table 1
by SIPPEL,KATHERINE H 29 Jan '10

29 Jan '10

Dear PHENIX programmers, I would like to preface this comment by saying that I love your suite of programs. I have converted to a 100% PHENIX fan girl and am dragging the rest of my lab down with me. I realize that you have a lot on your plates right now, what with all the bug fixes, updates, and bulletin board troubleshooting that you do. I am also primarily a biologist and have no comprehension of the effort required to keep everything running, but I do have a suggestion/request. I was putting the finishing touched on the first draft of a manuscript today and thought to myself, wouldn't it me wonderful if PHENIX could generate that all important crystallographic Table 1. You know the one that I am talking about with the data and refinement statistics. I am thinking a combination of PDB_EXTRACT and MOLEMAN where you input the log files from scaling and refinement and it outputs a handy-dandy test file with "parameter<tab>number that could easily be imported into your favorite spreadsheet (Open Office or Excel). I envision an interface with check boxes for the parameters you want to include and a place were you could input the resid of ligands for atom and b-factor counts. Like I said it is just a suggestion, in case you find yourselves bored and with time on your hands. Thanks for your time, Katherine -- SIPPEL,KATHERINE H Ph.

phenix.pdbtools and anomalous?
by Kay Diederichs 28 Jan '10

28 Jan '10

Hi, I like the way I can obtain Fcalc with phenix.pdbtools --f-model. However I need to have the anomalous signal as well, for certain atoms, and a given wavelength. This does not seem to be possible with phenix.pdbtools. Is there a way to do this with phenix.refine ? thanks, Kay -- Kay Diederichs http://strucbio.biologie.uni-konstanz.de email: Kay.Diederichs(a)uni-konstanz.de Tel +49 7531 88 4049 Fax 3183 Fachbereich Biologie, Universität Konstanz, Box M647, D-78457 Konstanz This e-mail is digitally signed.

Re: [phenixbb] refinement with alternative molecules?
by Su-Chang Lin 28 Jan '10

28 Jan '10

Hi Ralf, I've done the refinement with alt. conf.. The occupancy is 0.58 for Mol A, 0.42 for Mol B. The maps look OK. R-factors drops a little bit. Before when I put Mol A in that region for refinement, I saw additional densities (a helix) for Mol B. When I put Mol B in the region for refinement, I saw additional densities (loops) for Mol A. Now with alt. conf. there are no additional densities. Can I use the occupancies for publication? Or do I need to do/check something else? Thanks!
