Scale and merge multiple data sets
by Sam Tang 05 Feb '17

05 Feb '17

Dear colleagues Hello again. I would like to scale and merge two different native datasets for a same protein complex (which semed to die off gradually in the beam) using the scale_and_merge tool. The error message was received "Multiple intensity arrays - please specify one: data_labels=I,SIGI data_labels=IPR,SIGPR" However I looked into the log file and I have actually included "data_labels = "IPR,SIGIPR,merged" . Perhaps I have missed something else in the setting? Regards Sam Sam Tang Biochemistry Programme, School of Life Sciences, CUHK

Failed to refine B factors of some residues and ligands
by Zhou, Tongqing (NIH/VRC) [E] 16 Nov '16

16 Nov '16

Dear All, I am refining a structure with diffraction to 2.2A resolution and 95 % overall completeness. Now the Rs are at 18% and 23%, respectively. But the program failed to refine B factors for several ligands, atoms had high B factors while showing positive Fo-Fc map around them. Occupancy was set to 1 and I also tried to reset B to mean B of the whole PDB. Any of you seeing this phenomenon? Thanks! Shown below is HEPES that has high B factor and positive density around it after refinement: [cid:[email protected]] Best regards, Tongqing Tongqing Zhou, Ph.D. Co-head and Staff Scientist Structural Biology Section Vaccine Research Center, NIAID/NIH Building 40, Room 4609B 40 Convent Drive, MSC3027 Bethesda, MD 20892 (301) 761-7068 (Tel) (301) 793-0794 (Cell) (301) 480-2658 (Fax) ****************************************************************************** The information in this e-mail and any of its attachments is confidential and may contain sensitive information.

Planarity restraint ignored when dist_esd equal to 0
by Keitaro Yamashita 28 Sep '16

28 Sep '16

Dear PHENIX developers, My colleague noticed that planarity restraint of a ligand was ignored when a cif file in CCP4 monomer library was given to phenix.refine. The cif file was $CLIBD_MON/3/3PG.cif. This was because phenix (mmtbx) ignores planarity restraint when dist_esd is 0. In the line 2055 of mmtbx/monomer_library/pdb_interpretation.py (phenix-1.10.1), plane_atom is not added to the list when (plane_atom.dist_esd in [None, 0]) is True. _chem_comp_plane_atom.dist_esd in 3PG.cif (ccp4-7.0) is all zero except the first atom in the plane definition. As far as I checked, there is no cif file where dist_esd of the first atom of plane is zero. At least, it would be helpful if phenix shows warning in this case. Best regards, Keitaro

Rotamers of unnatural halogenated amino acids
by ancacarl 26 Sep '16

26 Sep '16

Hi, I'm working on the refinement of a protein mutated with an unnatural amino acid that contains one bromine atom. This particular amino acid is present as two rotamers. I've managed to introduce and do refinements with these two unnatural, brominated rotamers in Phenix, but the problem is that when shooting the protein with X-rays about 30-40% of the bromine atoms get knocked off. This means that the sum of the occupancies for the bromine atoms of the rotamers needs to be less than 1.00. However, the total occupancy of all the other rotamer atom pairs must be 1.00. Is there a way in Phenix to refine rotamers of brominated, unnatural amino acids, and at the same time have the total occupancy less than 1.00 for the Br atoms only? Any advice how to solve this is welcome.

phenix.real_space_refine - mmcif output?
by Oliver Clarke 26 Sep '16

26 Sep '16

Any chance of getting mmcif output in phenix.real_space_refine? Or does it exist and I have just overlooked the option? Right now I can use mmcif as input, but the refined coordinates are still written as pdb (hybrid32). The PDB unfortunately doesn’t accept hybrid32, so I always need to convert to mmcif with phenix.pdbtools prior to deposition - no big deal but would make life easier for large-ish structures. Cheers Oli.

Registration open: Future of Fragments symposium - Diamond, 28/29 Nov 2016
by Frank von Delft 23 Sep '16

23 Sep '16

Dear all Registration is now open for the Future of Fragments symposium on 28/29 November at Diamond Light Source, UK. http://www.diamond.ac.uk/Home/Events/2016/Future-of-Fragments-Symposium.html Places will be tight, so register early to give us time to gauge whether we must adapt plans. _Overview_ Crystal-based fragment screening of novel protein targets linked to disease has truly come of age: Diamond's XChem facility has been operating a regular user program since 2015, with other synchrotrons soon to follow suit. A progression of user projects have confirmed the power of this approach to discover both diverse chemotypes and unexpected mechanisms of action, especially allosteric binders. At the same time, the continued success in unearthing a rich array of fragment hits has now decisively shifted the bottleneck onto the question of how to translate hits into high potency leads. This challenge has highlighted the need for efficient and scalable methodologies in the areas of library design, label-free assays, computational compound design and the synthesis of complex lead molecules. This symposium aims to highlight the opportunities that must be explored if routine fragment screening is to turn into routine lead discovery. The event will bring together speakers from diverse disciplines to help define the methodology, focus and goals for fragment screening in the coming years. The four sessions will cover: screening methodology; computational methods; new synthetic methods; and automated chemistry.

Weighting in phenix.real_space_refine
by Oliver Clarke 13 Sep '16

13 Sep '16

Hi all, How does phenix.real_space_refine deal with restraint weighting? Looking at the output of the program, I get the impression that it splits the model up into different chunks, and alters weights locally based on some model/map correlation metric - is this the case (and are there more specific details available), or how does it work otherwise? Cheers, Oliver.

rosetta installation
by Sebastiano Pasqualato 12 Sep '16

12 Sep '16

Hi there, I am trying to run Phenix Rosetta Refinement on my laptop, which is running MacOSX 10.11.6 (El Capitan) with XQuartz 2.7.9. I have followed the instructions on this page: https://www.phenix-online.org/documentation/reference/rosetta_refine.html <https://www.phenix-online.org/documentation/reference/rosetta_refine.html> and specifically Once you have both a Phenix installation and a Rosetta source distribution, you can build the hybrid system with this command (located in the Phenix tree): rosetta.build_phenix_interface nproc=X Unfortunately, when I do that, the building does not proceed flawlessly, but instead stops with the message the I report below. Has someone gone through the same and can tell me how to set up Rosetta to be used with Phenix?
