anomalous difference map
by CPMAS Chen 11 Oct '14

11 Oct '14

Hi, phenix users, A difference map is used to identify whether there is anything not-modeled, say some ligands, ions. Then when I generate anomalous difference map, I should not put the ligand(which contains Br) in the model, right? Or in phenix, after I put the Br-ligand in the model, I should not see the anomalous difference density at the site, right? Could anyone give me a confirmation of this? Thanks!

After running autobuild, the Rfactors were 26/39 (autobuild removed the first 30 residues from the Nter!) but the maps look much better. I ran a quick refinement with default settings and the Rfactors are now 31/39 and can now see the density for my peptide (absent in the model) coming up. I have a few questions- 1) When is a good time to start building the peptide into the density (should I wait until Rfactors improve significantly)? 2) If so, should I be masking the peptide density somehow so that further refinement doesn't flatten out that density? 3) What is a general good strategy for lowering Rfactors? (Esp if the gap between Rwork and Rfree is high..like 28/40 or so)? Thanks a lot, S -----Original Message----- From: Sneha Rangarajan Sent: Wednesday, October 01, 2014 12:54 PM To: 'Paul Adams' Cc: phenixbb(a)phenix-online.org Subject: RE: I think my problem in MR has been one of the chains. Anyway I tried the ideas you suggested and seems like they worked! I used ensembler to create a merged pdb of the problematic chain and used phaser giving both chains as multiple ensembles. It gave me a solution with LLG=474 (highest I have got so far) and TFZ=18.8. I also tried MRage and got a solution with LLG=294. In both these maps, the density for chain1 ("bad chain") is not as good as the other chain but is nonetheless far better than what I have got before. I am currently running autobuild on the solution hoping my Rfactors would be reasonable this time. Thanks a lot for your inputs. They really helped!!

In this case I suggest that the most likely issue is the search model (I assume your molecule is fairly small given the unit cell dimensions). I would look at ways to create the best search model using using tools like sculptor and ensembler. You can get Phaser to search for the two domains in the same run but using multiple ensembles. You might also want to try MRage in Phenix, where you can just provide the data file and the sequence and it will try to make the best model and solve the MR problem.

PDBe workshop on programmatic access to macromolecular structure information, 20-21 Nov 2014, Cambridge UK
by swanand＠ebi.ac.uk 06 Oct '14

06 Oct '14

=============================================================== Programmatic Access to the Macromolecular Structure Information =============================================================== -------- PDBe Workshop for Programmers, 20-21 Nov 2014 -------- ============= What? The Protein Data bank in Europe (PDBe; http://pdbe.org) is organising a hands-on, interactive workshop for developers interested in using primary and value-added information about the 3D structures in PDB and EMDB. Programmatic access to macromolecular structure data as well as information about assemblies, structure quality, literature and citations, and up-to-date cross-references to other biomedical resources (UniProt, Pfam, CATH, SCOP, etc.) is a critical requirement for integrative bioinformatics analyses and workflows. PDBe has developed a set of REST APIs (http://wwwdev.ebi.ac.uk/pdbe/api/doc) that provide easy access to high-quality information regarding biomacromolecular structures archived in PDB and EMDB. They provide a simple, reliable, light-weight mechanism to query macromolecular structure data, select entries or molecules of interest, and access targeted information about them, including information about the molecules, experimental details, assemblies, motifs, function, taxonomy, structure quality, etc. The API is used by the PDBe services and is also integrated in Jmol/Jsmol. We will also present Solr/Lucene based query API for macromolecular structure information including PDB, EMDB and value added information on assemblies, structure quality and up-to-date cross-reference infromation to other biomedical databases based on SIFTS (http://pdbe.org/sifts) . ============= Is it for me? Do you (plan to) develop software or on-line resources that use or need access to information about structures in PDB or EMDB? Would you rather not maintain your private infrastructure for retrieving, parsing, storing and updating such information? If so, then this workshop is for you! In the workshop, we will explain what information is available through the API and how you can access it from your own software or resource. There is plenty of time for hands-on work where experienced PDBe developers will try to help you use the API for your specific needs. ============= When? 20 & 21 November 2014. ============= Where? EMBL-EBI (http://www.ebi.ac.uk) , Cambridge. ============= How much does it cost? We expect you to pay for (and arrange) your own travel to and from Cambridge. However, there is no fee for the workshop, and we will provide free accommodation (Holiday Inn Express; http://www.hiexpresscambridgeduxford.co.uk), transportation between the hotel and the EMBL-EBI, coffee/tea, lunches and a workshop dinner on the 20th. This is all thanks to generous funding from the Wellcome Trust to PDBe. ============= How can I apply? E-mail Swanand Gore (swanand(a)ebi.ac.uk) or Jose Dana (dana(a)ebi.ac.uk) at PDBe no later than 20 October 2014 with the following details: * a brief description of the software you have developed or are developing - i.e. what it does, in which field, how many users, relevant publications, etc. * programming language(s) you are specifically interested in (python examples and tutorials will be provided). * how you would benefit from this workshop. * any specific topics or questions you would like to see addressed in the workshop. If the workshop is oversubscribed, we will select participants based on the information provided. You will be informed by the end of October if you have been selected or not, or whether you are on the stand-by list. ============= Prerequisites? Basic programming experience in use of REST API’s. Bring your own laptop with git and iPython notebook pre-installed if you want to follow the python tutorial and examples. If you need to make plots, make sure that matplotlib is also installed. ============= Questions? Swanand Gore (swanand(a)ebi.ac.uk) or Jose Dana (dana(a)ebi.ac.uk) at PDBe will be happy to answer your queries.

Problems building source
by Jason Swails 02 Oct '14

02 Oct '14

Hi everyone, I'm a new user that is trying to get Phenix installed. I'm trying the source build since I want to poke around with a little development. I haven't had much luck in this endeavor (I'm fairly competent when it comes to building especially scientific software from source). What I tried was untarring the 1.9-1692 release tarball and running ./install in that directory. The first thing to fail was Imaging, and the build log complained of a missing freetype/fterrors.h header. On my machine, that file is located in /usr/include/freetype2/fterrors.h. OK, so I symlinked /usr/local/include/freetype to /usr/include/freetype2 and tried again. Imaging succeeded, but then I noticed that Phenix tried to compile its own version of freetype later (!). I'm curious as to why it would either a) not build freetype first so Imaging could use it or b) why it would try to build freetype at all when it already has to be installed. Anyway, after that was done, I got another problem when the install process got to Pango. Then I get the error: fribidi_config.h:1:18: fatal error: glib.h: No such file or directory But glib has already been installed according to the Phenix install log (and I have it installed on my system, too). There's a glib.h in tmp/glib-2.12.11/glib/glib.h (but that directory is never added to the include search path), and also in /usr/include/glib-2.0/glib.h. I admit that the install process has me puzzled (for instance, I can't figure out how to augment CFLAGS for the Pango install to make it find glib.h), and I feel that I'm playing a bit of whack-a-mole with the build problems here... Any help or advice regarding getting the source code built is appreciated. Thanks! Jason -- Jason M. Swails BioMaPS, Rutgers University Postdoctoral Researcher
