pdb help
by jp d 20 May '17

20 May '17

hi, phenix version 1.11.1-2575 FEM has crashed a few times for me . i have tried using various parameters (resolution_factor=1./3, use_resolve=False) , but it will max out my RAM (24G) and get into swap space. It gets very memory intensive, i think thats why it crashed. Do you have any suggestions to try ? i previously had a similar problem with a pdb using conflicting chain assignments, but this pdb doesn't use chains thanks jpd

Electronic Laboratory Notebook
by Sebastiano Pasqualato 19 May '17

19 May '17

Dear all, another enquiry for the great community! We are considering the idea of moving to electronic laboratory notebooks rather than paper ones. Are you happily using one and would warmly suggest its implementation? Our department does not only deal with biochemical experiments, but performs a lot of genomics (big data analysis) and mouse genetics experiments, so experience of Notebooks used in departments that also have those activities would be a plus. We will consider free and paid softwares, if you have information on the costs that would be also very much appreciated! Thanks a lot, ciao Sebastiano -- Sebastiano Pasqualato, PhD Crystallography Unit Department of Experimental Oncology European Institute of Oncology IFOM-IEO Campus via Adamello, 16 20139 - Milano Italy tel +39 02 9437 5167 fax +39 02 9437 5990 web http://is.gd/IEOXtalUnit

phenix real space refine & free R reflections
by Hillen, Hauke 06 May '17

06 May '17

Dear Phenix bb, I have a rather conceptual question regarding the treatment of free R flags in phenix.refine and phenix.real_space_refine. I am refining an xray structure using phenix.refine (but not using the real space refinement implemented there) and at some point decided to play a bit with the standalone program phenix.real_space_refine. In particular, I was interested in testing real space refinement against different maps (experimental map vs. model-phased). Being used to the excellent handling of free R flags in Phenix, I assumed giving phenix.real_space_refine the output MTZ of a previous phenix.refine run as a map would be safe to do. But I then saw the phenix.refine FAQ states the following: "Are R-free flagged reflections included in the maps used for real-space refinement? No, this is almost guaranteed to bias R-free; these reflections are removed internally prior to map calculation. However, the output maps will include these reflections unless you explicitly request otherwise.” While it makes sense to me that including the free reflections in the maps used for real space refinement will bias R-free, I wonder why the default behavior of phenix.refine is to output maps which include these reflections. I assume most users will use these output maps (for example via the OPEN IN COOT button in the GUI) to iteratively improve their model by local real space refinement in Coot. Conceptually, how is real space refinement performed by phenix.refine (where the free R reflections are not used to calculate the map to refine against) different from manual local real space refinement in Coot? Will the latter not also bias R-free when the default output maps from phenix.refine are used? Best, Hauke

Different stats with different number of macrocycles
by Patrick Loll 05 May '17

05 May '17

Hi, I have an odd observation. I am finishing a refinement at 2.5 Å, using the Phenix GUI. I performed a three-macrocycle refinement, and saw that the geometry (RMS bonds/angles) and R/Rfree all got better in the first macrocycle, and then worsened in the subsequent two macrocycles. OK, fine. So I repeated the refinement, except I performed only a single macrocycle (starting from the exact same input coordinates). However, the statistics after this one-macrocycle job did not match the stats seen after 1 macrocycle in the 3-macrocycle job (?!). This doesn’t make sense to me; if you’re starting from the exact same coordinates, shouldn’t the first macrocycle always wind up at the same place, regardless of whether or not the program goes on to do additional macrocycles of refinement? In case this isn’t clear: In the 3-macrocycle job, after the first macrocycle, RMS bonds/angles = 0.005 Å/0.9 deg, R/Rfree = 0.208/0.236 (by the end of the third macrocycle, these numbers have changed to 0.009 Å/1.41 deg and 0.212/0.244) At the end of the 1-macrocycle job, RMS bonds/angles = 0.008 Å/1.4 deg, R/Rfree = 0.209/0.240 This is Phenix version 1.11.1-2575-000. Any insights welcome. Cheers, Pat --------------------------------------------------------------------------------------- Patrick J. Loll, Ph. D.
