Non crystallographic symmetry
by Reza Khayat 02 Oct '15

02 Oct '15

Hi, I need to use icosahedral symmetry to refine a virus crystal structure. Does phenix support 60 NCS matrices? If not, how should I go about recompiling the program so that I can have 60 NCS matrices? Best wishes, Reza Reza Khayat, PhD Assistant Professor City College of New York Department of Chemistry New York, NY 10031

on phenix.refine
by Smith Liu 30 Sep '15

Dear All, If my protein contains a metal ion (Mg2+ for example, do I need a cif for the metal for phenix.refine? If my protein contains another ligand, which server can produce the ligand PDB suitable for the eLBOW? If my protein contains 2 ligands, then do I need 2 cif files for the phenix.refine or the phenix.real_space_refine? I am looking forward to getting your reply. Best regards. Smith

on Phenix10
by Smith Lee 28 Sep '15

28 Sep '15

Dear All, With the EM cryo data, I have compared the function of phenix.real_space_refine of Phenix10 and Phenix1.9-1692. For the Ramachandran favored, the new version is about 90%, the old version is about 92%. For the clashscore by Molprobity, the new version is about 30, the old version is about 20. Molprobity indicated the clashing atoms were systematically existing in the whole molecule, rather than on specific parts of the protein which may be indication of bad modelling. Clearly the clashscore of 30 is unacceptable. Will you please give some advise on how to improve the function of new version of Phenix, considering adding H was not suitable as for the resolution was poorer than 4.0 A? Smith

just a wild guess - could it be that, according to http://strucbio.biologie.uni-konstanz.de/ccp4wiki/index.php/Phenix#Installa… the Phenix installer requires (on Fedora and RHEL) the openssl-devel and libXt-devel to be installed on the system ?

Rosetta refine compilation issue Centos 7
by ludovic Pecqueur 24 Sep '15

24 Sep '15

Dear Developers, I have a fresh Centos 7 system and after installing Phenix I wanted to compile the Rosetta.refine module. (Rosetta from source version 2015.31.58019) I have succesfully compiled Rosetta but when I try to build the dedicated Rosetta for Rosetta_refine with rosetta.build_phenix_interface after setting up PHENIX_ROSETTA_PATH and ROSETTA3_DB I get the following error message: [XXX@...]$ rosetta.build_phenix_interface nproc=6 False scons: Reading SConscript files ... Running versioning script ... Done. (0.1 seconds) Could not find platform independent libraries <prefix> Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] ImportError: No module named site CalledProcessError: Command '['./update_options.sh']' returned non-zero exit status 1: File "/usr/local/PROGRAMS/ROSETTA/PHENIX_Rosetta_refine/main/source/SConstruct", line 172: main() File "/usr/local/PROGRAMS/ROSETTA/PHENIX_Rosetta_refine/main/source/SConstruct", line 163: SConscript("SConscript", "build") File "/usr/local/PROGRAMS/ROSETTA/PHENIX_Rosetta_refine/main/source/external/scons-local/scons-local-2.0.1/SCons/Script/SConscript.py", line 614: return method(*args, **kw) File "/usr/local/PROGRAMS/ROSETTA/PHENIX_Rosetta_refine/main/source/external/scons-local/scons-local-2.0.1/SCons/Script/SConscript.py", line 551: return _SConscript(self.fs, *files, **subst_kw) File "/usr/local/PROGRAMS/ROSETTA/PHENIX_Rosetta_refine/main/source/external/scons-local/scons-local-2.0.1/SCons/Script/SConscript.py", line 260: exec _file_ in call_stack[-1].globals File "/usr/local/PROGRAMS/ROSETTA/PHENIX_Rosetta_refine/main/source/SConscript", line 28: subprocess.check_call(["./update_options.sh"]) File "/usr/local/PROGRAMS/XTAL/PHENIX/phenix-1.10-2155/base/lib/python2.7/subprocess.py", line 540: raise CalledProcessError(retcode, cmd). If you have any idea of what could cause the problem, I would welcome any suggestions. I updated Phenix and I could compile phenix.rosetta_refine without problems on Centos 6.7. Thank you very much for your time and help. Kind regards, Ludovic.

a question on phenix refine
by Smith Liu 23 Sep '15

23 Sep '15

Dear All, If my protein is rather large, and I have the mtz file of the whole protein, when I do phenix.refine of a single domain PDB of the whole protein against the whole protein mtz, after several cycles of phenix.refine the domain will not fit in the map at all (or even the domain moves far away from its initial position in map which it fits best), perhaps because the phenix.refine has made the domain to seek suitable fit in the map. Is any possibility at the whole process of phenix.refine we keep the domain relatively surround the map position where it fit best, so that phenix.refine will really do the refine in this situation? Best regards. Smith

ADP restraints under TLS+individual ADP
by Tristan Croll 23 Sep '15

23 Sep '15

Hi, When taking a structure I refined in Phenix (using a TLS + individual ADP model) into a different refinement package, a colleague noted a host of warnings related to mismatched B-factors between the sulfur atoms in disulfide bonds. If I understand correctly, this arises due to Phenix falling back to a Ulocal only ADP restraints scheme and, in particular, the choice to set adp_restraints.iso.sphere_radius = 2.0. The length of a disulfide bond being 2.05A, this means that as long as the geometry is correct the B-factors of the two sulfurs are never restrained to each other under these conditions.

labelit distl_minimum_number_spots_for_indexing
by Christian Roth 22 Sep '15

22 Sep '15

Dear Phenix-Team I installed the latest nightly build 1.8-1069. I tried to index some diffraction images and to overwrite the minimum usable spots for indesing I tried the suggested command. However If I try this command, it seems that it does not exist. At least in the list of the possible distl commands it does not show up. Do I have to install some additional stuff or change some preferences to get this command? Best Regards Christian

Alternative conformations in Coot
by Nigel Moriarty 21 Sep '15

21 Sep '15

Folks A recent article by Pavel Afonine in the Computational Crystallography Newsletter highlighted the flexible interface for alternative locations in Phenix. You can read it here: http://phenix-online.org/newsletter/CCN_2015_07.pdf#page=12 It recently came to my attention that some users who have an example of the Number 5 were having trouble viewing their models in Coot. After communicating with Paul Emsley, it turns out that you need a recent version of Coot (I ungraded from 0.8 to 0.8.2) and add the line allow_duplicate_sequence_numbers() to your ~/.coot.py file. You can test this using PDB 1ejg. Cheers Nigel --- Nigel W.

5'-phosphate group CIF files
by jens j birktoft 21 Sep '15

21 Sep '15

Hi everyone I need some suggestions for a CIF file for a 5'-phosphate moiety that is part of the nucleotide (CYT in this case) located at the start of a DNA strand (5' end) to be used in refinement in both PHENIX and COOT. All suggestions are appreciated. Cheers Jens -- +++++++++++++++++++++++++++++++++++++++++++++++++++ Jens J.
