mr_rosetta fails after autobuild stage
by Huw Jenkins 01 Mar '13

01 Mar '13

Hi, I've been having some problems with mr_rosetta. All the regression tests run fine but when I run it on some real data it gets as far as the autobuilding stage and then fails with an error message. All I can find in the log files GROUP_OF_AUTOBUILD_1/RUN_FILE_1.log GROUP_OF_AUTOBUILD_1/RUN_FILE_2.log is ******************* ERROR ENDING *************** Failed to carry out autobuild ******************* ERROR ENDING *************** The autobuild jobs themselves seem to finish fine i.e the end of the log files in GROUP_OF_AUTOBUILD_1/RUN_1/AutoBuild_run_1_ and GROUP_OF_AUTOBUILD_1/RUN_2/AutoBuild_run_1_ has the tables of Rfactors per cycle and the list of citations with no indiction of any error. Is there anywhere else I should be looking for a more detailed error message? Thanks, Huw

real_space_correlation
by Jianghai Zhu 28 Feb '13

28 Feb '13

Hi All, I was trying to use "phenix.real_space_correlation *.pdb resolve_composite_map.mtz" to get some real space cc for my ligand against the SA composite omit map. But I am not sure that the map used here was the SA composite omit map. Will phenix use the omit map I provided or will it just simply calculate a sigmaA weighted 2Fo-Fc map based on the pdb? Thanks. --Jianghai

mr_rosetta: two proteins, one chain placed, build second chain
by Tobias Beck 28 Feb '13

28 Feb '13

Dear phenixbb, I would like to use mr_rosetta to build a second protein chain. For the first protein, I have a search model with known structure. The search model can be placed with Phaser (TFZ 10). For the second protein, the structure of a homologue has been determined. The second protein accounts for about 2/3 of the residues in the ASU. I would like to fix the first protein chain and build the second protein chain with mr_rosetta. I have obtained fragment files for both proteins from robetta. What input parameters are required to tell mr_rosetta to build the second chain only? I have tried the fixed_ensemble_ID_list = ensemble1 option. Here is an excerpt of my parameter file with the input files: run a) search_models = "path/chainA.pdb" (from Phaser) search_models = "path/chainB.pdb" (homologue structure) fixed_ensembles { fixed_ensembleID_list = ensemble1 fixed_euler_list = 0.0 0.0 0.0 fixed_frac_list = 0.0 0.0 0.0 fixed_frac_list_is_fractional = True } alignment_files = "path/chainA.dat" alignment_files = "path/chainB.dat" with chainA.dat having twice the same sequence and chainB.dat with the target and template alignment. I have set fragment files with chain_list for both chains. I get this error when running phenix.mr_rosetta (running from command line with .eff file) "Sorry, the file /path/GROUP_OF_PLACE_MODEL_1/RUN_2/chainB_al_0.pdb representing group 0 has no atoms? This could indicate a problem with sequence alignment in rebuilding. It could be that there are near-duplicate sequences in your sequence file ...if this is the case then you may need to artificially rename your duplicated chains and renumber residues to make a single chain containing a duplication" This error also occurs run b) Without any alignment files run c) Without any alignment files and with just chainA.pdb as search model. An alignment of the sequences from chainA and chainB gives low identity (no duplicate regions), so I suspect the problem is located somewhere else? I have seen a post by Tom Terwilliger, explaining how to deal with two identical chains with different conformations where no alignment files are required. However, I would like to use the information from the homologue structure, that is why I specified the alignment file. By inputting chainB.pdb as search model, mr_rosetta also tries to use this model as a search model for molecular replacement, but I think this is not necessary (and gives a warning that the space group of the search model and the data file do not match). I just want to provide the structural information from structure chainB.pdb to mr_rosetta for building. ----- So in summary this is what I would like to do: chain A: keep fixed - use chainA.pdb as fixed model chain B: build - use information from homologue structure (chainB.pdb) and fragment files to build chain What is the best strategy to do this? What input parameters are required so that I do not get the error described above? ----- Thanks a lot in advance, Tobias.

phaser output and packing
by Ursula Schulze-Gahmen 26 Feb '13

26 Feb '13

Could somebody explain to me how phaser decides if there is a solution. When I look at the log file there are a few solutions in the translation function that have fewer than the allowed clashes, but they are still not recognized as potential solutions. Why is that. Is there another parameter that I should be looking at? Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

Maximum Entropy Maps
by Morten Groftehauge 22 Feb '13

22 Feb '13

Hi guys, I see that phenix.maximum_entropy_map is now a command in Phenix. Some quick questions: Where is this likely to be must useful and does it take ridiculously long to run? From the Nishibori 2008 paper in Acta D it seems like this would mainly be useful for very high resolution structures that you would normally call complete - and that it would take a very long time to compute. I love trying out new methods but I need a bit more to go on with this one. Cheers, Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

Building sugars
by Folmer Fredslund 21 Feb '13

21 Feb '13

Dear all, What's the "correct" way to build and refine sugar polymers? I am currently building several structures with different kinds of sugar polymers bound to them. Searching for similar "ligands" in the PDB, I end up with e.g. trisaccharides that are named as one molecule, even though they are indeed made up of three individual sugars with bonds between them. Thank you for any pointers. Best regards, Folmer -- Folmer Fredslund

cut out density vs FFT
by Yunji Wu 19 Feb '13

19 Feb '13

Hi all-- I'm trying to make a 2Fo-Fc map with density wrapped around my asymmetric unit to make a figure showing density for my sub-8Å structure. I am not building into this map or doing MR. My model was refined in Phenix.refine (R's in the high 30's), and so I have the output model .pdb and the output map coefficients .mtz. When I input these into cut_out_density, the only "map labels" input options it gives me are 2FOFCWT, PH2FOFCWT, which seem fine. Using either box, sphere, or model for the cutout type, I get a VERY nice looking map that looks extremely solvent flattened and tight around my model, albeit still to 8Å. Suspicious of anything that looks good, I went to try the same thing in FFT (CCP4). There I generated a simple map (using the same .mtz) to cover all atoms in a pdb file- the same model I put into cut_out_density. For the input I selected 2FOFCWT and PH2FOFCWT, leaving Sigma and Weight unassigned. The map that comes out of this looks terrible, with a lot of noise and little density corresponding to the model aside from what one might expect from a very poor resolution experimental map. I've also tried using FFT in Phenix to do the same thing, and it gives like better maps than CCP4 FFT but worse than cut_out_density. It almost appears as if there is some additional solvent flattening going on, which I know happens at the beginning of refinement, but that should be intrinsic to the map coefficients file which is common to everything I've tried. My questions are (1) what should I use for what I am trying to do (just display 2Fo-Fc density around asymmetric unit for a figure) and (2) what is the difference between what these three programs (cut_out, FFT-CCP4, FFT-Phenix) are calculating? The inputs are exactly the same -- mtz (2FOFCWT and PH2FOFCWT) and pdb output from refinement. Thanks for the help, Yunji

Problems placing second component in Phaser
by Morten Groftehauge 19 Feb '13

19 Feb '13

Hi guys, So I have a solution that covers some of target and I ran it through phenix.mr_rosetta and I am actually kinda happy with the output from there. However, while I can place both (NCS=2) with the original model I only seem to be able to place one of the rosetta models, even with 'packing function' set to 'all' or 'allow'. Original model - Refinement after placing component 1: LLG 175 Refinement after placing component 2: LLG 620 Rosetta model (packing 'all') - Refinement after placing component 1: LLG 295 Refinement after placing component 2: LLG 390 Rosetta model (packing standard) - Refinement after placing component 1: LLG 295 Refinement after placing component 2: LLG 350 More notably there is little to no increase in TFZ with the placement of the second component... There are more residues in the Rosetta model and I would expect more clashes but this looks weird. Cheers, Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

Dear user, I have problem in finding the phase for the flexible DNA binding domain of LTTR protein. The unit cell parameters are ,Unit Cell: 46.92 105.30 47.75 90.00 103.26 90.00, and space-Group P 1 21 1. Molecular weight of protein is 36000Da. When i am running phaser it showing that Most probable MW of protein in asu for resolution = 49714.8. Could you please guide me how to set the proper setting for finding the correct rotation function and translation function setting to get the phases for the full length protein. I m getting the phases for the ligand binding domain but not for the DNA binding domain. Could you please suggest me some tricks which would work to get the phase. Thanks a lot in advance. Appu

Trouble with Phenix
by Rachel North 17 Feb '13

17 Feb '13

Hi, I have been having some issues with Phenix. When I input the mtz file (generated from CCP4), an error message appears... "File format error: cctbx Error: invalid combination of values while extracting anomalous array from columns: F New, SIGF New, DANO New, SIGDANO New, hkl= -3,25,44." This happens when I try to use the reflection file editor, xtriage and phenix refine. I have tested datasets collected from other crystals in the same condition and still have the same problem. I have also tried to process my data using different programs (XDSME and iMOSFLM) before going to CCP4 and then Phenix for refinement. I have never had this problem before and I have run every program on CCP4 the same way that I usually do. Does anyone know how I fix this or where I am going wrong? Kind Regards

HETATM automated chain assignment
by Talon Romain 15 Feb '13

15 Feb '13

Hello to the Phenix bulletin board community, I would like to know if I could find a tool to automatically assign HETATM atom (or even, water molecules) to the nearest protein chain ? In my case, I have 4 protein chains in the asymmetric unit : A, B, C and D. I would like to assign each ions and each ligands (which are numerous) with the chain letter of the nearest residue that coordinate them. Usually, I rename everything by hand but as the in-house program of the PDBe AutoDep deposition tool automatically do that... I beg your pardon if this question has just been posted here. I didn't find any tool either in the Phenix Suite or in the "Extensions" and "Calculate" menus of the Coot program (v0.7). Best regards. Romain Talon

Excellent point. The difference between using bme and cme is rather ideological. I would say that incorporating cme implies that your protein was somehow synthesized with non-canonical amino acid. Usind bme seems more in line with what actually happens - betamercaptoethanol forming disulfide bond with a cysteine. In practical sense, both things work.

FW: phenixbb Digest, Vol 87, Issue 3
by Phoebe A. Rice 10 Feb '13

10 Feb '13

Hi, Although its theoretically possible, I've never had 5-Br-dU cause a problem. My approach would be to pick the strand with more T's and get every T replaced with 5-Br-dU, unless the 3' nt is a T (you pay a lot more for 3' modifications). We have had issues where crystals wouldn't grow with a heavily 5-I-dU modified DNA, presumably because Iodine is significantly bigger than a the 5-methyl of T, and it annoys the protein. If you've got good footprinting data, you may be able to guess where the protein will "care" about the surface of the major groove, and avoid putting iodines in those regions. If not, its probably faster to just order several oligos and try them all. If you've got a lot of T's and are worried about locating all those heavy atoms, I'd go for one derivative with a couple of paired 5-I-dU's (in spots where you have two T's in a row) in hopes that that will give you a toehold on solving the Patterson, and then a 2nd where every T on one strand is brominated, which may provide more phasing power. Note that both of these pop off in the x-ray beam, so collect your anomalous data first and fast. Also note that if you're lucky, you can get an extra large delta f' by subtracting the last data set from the first ("radiation induced phasing"). Hope that helps!

phaser for long thin molecule
by Ursula Schulze-Gahmen 08 Feb '13

08 Feb '13

I am doing molecular replacment for a very elongated molecule in phaser. I would like to try different values for the maximum patterson cutoff but I am not sure which parameter I need to change in the phenix version of phaser. Does somebody have experience with this? Thanks Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

How to model domain-wide disorder in Phenix.refine (turn off bump interactions) ?
by Phil Jeffrey 08 Feb '13

08 Feb '13

Hi, I've got a pernicious problem where the electron density for one domain appears to extensively interpenetrate another similar domain. I'm in the process of trying to work out things like: MR solution in the wrong space group courtesy of pseudo-centering. In the meanwhile I want to model it as interpenetrating domains, and need to turn off VdeW bumps at the domain (chain) level of structure. I can't just model it as a infinite list of alternate locations. I (think) I remember how to do this in CNS (constraints interaction), but is there a way to do this in phenix ? I could not track down a particularly promising section of either the manual or the .def/eff file(s). Thanks Phil Jeffrey Princeton

Designing heavy atom positions on my DNA crystal
by Xiang Li 06 Feb '13

06 Feb '13

Hi everyone, I am trying to grow my DNA crystal with bromide derivatives. The content in one asymmetric unit is a 30 bp DNA duplex. I am considering about how many bromides modified bases should I use to ensurethe strong enough heavy atom signal. Also where to put these bromides? To my understanding, maybe I should put the heavy atoms at the most rigid places, avoiding the clashes and not too close to other heavy atoms. I have few experience on this and hope you could give me some help on the design. Thanks a lot! Sincerely, Xiang

Phaser annoyance
by Morten Groftehauge 05 Feb '13

05 Feb '13

Hi guys, The pop-up warning from Phaser about lack of eLLG for the resolution of the data would be more informative if you added the value of eLLG so one wouldn't have to scroll back in the log to find it. It would also allow the user to see with a glance whether the warning is because eLLG is under 120 or under 60. And it seems like the 'non-simple' Phaser GUI is broken in 1.8.2-1288. At least I haven't been able to open it, neither from the main window or by opening a previous job (Ubuntu 10.04). Cheers, Morten -- Morten K Grøftehauge, PhD Pohl Group Durham University

MR: Apply rotation and translation to structure factors
by Shweta Kailasan 01 Feb '13

01 Feb '13

Hello, I am trying to use a cryo-EM map as a MR model for an Xtal data set. I have calculated structure factors for my map using SFALL. And also used rotcross and trans.com (from AMORE) to determine best possible rotation and translation solutions. Is there is a program/script available that can be used to apply those rotations and translation to structure factors ? Most programs start with a coordinate file (pdb) as a model whereas my initial model is a map. I tried to use Phaser but it didnot work out. Any help would be highly appreciated. Thank you. -S <peter.ramsumair(a)credit-suisse.com>

Hirshfeld (rigid bond) test
by amakal＠chem.uw.edu.pl 31 Jan '13

31 Jan '13

Good Morning, I have a question concering ADP-s analysis and validation. Thanks to the recent discussion on this list I learned about the tools for general ADP-s statistics and average B-factor plotting in PHENIX. Has anyone ever tried to similarly document/visualize the values of the Hirshfeld's rigid bond test for macromolecules, using phenix/cctbx tools? I know the Hirshfeld's can be calculated during phenix refinement (there is this rigid_bond_test keyword), but I would like to analyze the values for the final model... With regards, Anna Makal

Hi guys, I'm just trying to install phenix on a students new macbook pro running OS10.8.2, and want to get phenix.refine working on the command line. I've put in: alias setphenix="source /Applications/PHENIX-1.8.1-1168/Contents/phenix-1.8.1-1168/phenix_env.sh" in the .bashrc which seems to execute OK (and already pointed the .bash_profile to .bashrc) however whenever I then type phenix.refine I get command not found. As this is the same setup that I have running on my own machine I am a bit confused as to what is happening! Thanks! Simon

Phaser with fixed solution
by Ursula Schulze-Gahmen 30 Jan '13

30 Jan '13

I am trying to solve a structure by molecular replacement in phaser using 2 model fragments. I think I may have placed the 1st fragment correctly. I don't quite understand how to best proceed with a fixed ensemble searching for the second fragment in phaser-MR. If I select "use partial solution from previous job", do I still need to read in the coordinates of that previous solution for one ensemble? And If I do, should I read in the starting coordinates or the placed output from this 1st molecular replacement? The second question is about how to relax the restraints fr the packing. In the "other settings" sub window is a section for packing. Could someone explain to me what the different options in this packing section mean? Which of them should I change to allow for more close contacts? Thanks Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

Re: [phenixbb] Unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 bits
by Kay Diederichs 29 Jan '13

Davi, This looks to me like you tried installation using e.g. the fc14 installer (that has a glibc "too new" for SL6), and installed with the fc3 on top of that (SL6 works well with the fc13 or lower installer). Since the installers write to the same directory, the fc3 installer finds that the files are already there and does basically nothing that would fix the problem, i.e. replace the binaries and libs. So just remove the /usr/local/phenix-1.8.1-1168 directory (or its contents) before you try a different installer.

use of the file find_ncs.resolve
by Fred. Vellieux 29 Jan '13

29 Jan '13

Hi all, I do not understand how the file "find_ncs.resolve" has to be fed into the "resolve" part of Phenix. Can it be used in the GUI for an autobuild procedure? Can anyone help on this?

Add restraints between base-pairs in GUI & structures comparison
by Xiang Li 28 Jan '13

28 Jan '13

Hi everyone, I am a new user of Phenix and have a few questions asking for help. 1 I worked on a DNA structure and wanted to add restraints during the refinement. I used GUI version and chose "secondary structure restraints"->"restraint base pairs". However, there were some distortion of the base pairing after refinement. Is there a way to assign the base pairing between specific base pairs and force the base pairings in the GUI version? 2 I want to compare two DNA structures to see the RMSD. Each of them were composed of 4 strands. Seems "structure comparison" software can not work with such multiple strands DNA structures. Do you have any suggestions on how to do the comparison please? Thank you very much for your reply! Sincerely, Xiang

multiple occupancy
by Damian Niegowski 28 Jan '13

28 Jan '13

Hi all, I´m trying to refine a dataset which seems to have two different ligands with partial occupancy in the same active site. How do you refine this? When I put them over each other with say 50/50 occupancy Phenix either moves the ligands apart or mashes the two molecules into one strange composite ligand. In Refmac this works without any special settings, it accepts the occupancy distribution between the ligands. Any ideas?

Unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 bits

Dear all, I am unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 bits. Hence, I would greatly appreciate any 2 cents (or diamonds). I installed Scientific Linux 6.3 64 bits, updated everything and installed a couple of things that I think would be necessary. Then I uncompressed phenix-installer-1.8.1-1168-intel-linux-2.6-x86_64-fc3.tar to /tmp and tried to install, however I got some errors. Hence, I installed a couple more things and tried installing again.

Fwd: WCPCW 21
by Nathaniel Echols 25 Jan '13

25 Jan '13

---------- Forwarded message ---------- From: "Williams, John Charles" <jwilliams(a)coh.org> To: "PHENIX user mailing list" <phenixbb(a)phenix-online.org> Date: Fri, 25 Jan 2013 16:22:00 -0800 Subject: WCPCW 21 All A couple of people requested an extra day or two to register. So we have extended the standard registration fee once more to Tuesday, Jan 29th. As we have to submit our room list Feb 1 to get the room rates at discount, this has to be the last extension. Of note, the meeting is 'all inclusive' - registration includes the meeting, lodging, and all meals (breakfast, lunch and dinner, coffee breaks, and social hours). That said, WCPCW21 is quite full, but we can accommodate a few more. In addition, we have not yet started to select posters for oral presentations. So it is still possible, especially for graduate students and postdocs, to give an oral presentation. Look forward to meeting every one in Monterey! Best, John

RapiData: Seats are available - the deadline is in 10 days for our course on Data Collection and Structure Solving at the NSLS.
by Robert Sweet 25 Jan '13

25 Jan '13

We will present RapiData 2013, the fifteenth offering of our popular course: Rapid Data Collection and Structure Solving at the NSLS: A Practical Course in Macromolecular X-Ray Diffraction Measurement The course will be held 21-26 April 2013: http://www.bnl.gov/RapiData/. Students could be at any level from advanced undergraduate to full professor. The course should accommodate 48 students total. We encourage all students to bring their own specimens for data collection, and to bring old data for the data-reduction and structure-solving tutorials. Please read the Course Announcement at http://www.bnl.gov/RapiData/. You'll see that many experts in the field will be available for lectures and tutorials. You'll find the application materials on the Course Application tab at this site. For the eleventh time we will hold a short lecture course on the fundamentals of crystallography for roughly five hours on Sunday 21 April. The body of the RapiData course really requires that students have a healthy knowledge of crystallography. For potential students who have some experience but are shaky about fundamentals, this course will help. There will be a small additional fee for the fundamentals course, to pay for Saturday night accomodations and food on Sunday morning and noon. Latin American Scientists: Several scholarships are available, from the International Union of Crystallography, to pay partial travel and subsistence costs for Latin-American students and junior faculty (under 40 yrs). Please apply for the course, and then contact R. Sweet (sweet(a)bnl.gov) if you are interested in applying for a scholarship.

B-factor calculation
by Wei Shi 24 Jan '13

24 Jan '13

Hi guys, I am wondering how I can calculate average B-factor in phenix GUI. I read from an old post saying that, the following will give me complete statistics about B-factors, but in pdbtools in phenix GUI, I didn't find how to show adp statistics. phenix.pbdtools your_model.pdb --show-adp-statistics Besides, I am wondering how I can find the B-factor for each residue and plot the variation of B-factor by residue. Thank you so much! Best, Wei
