pdb_as_cif
by jp d 15 Jan '15

15 Jan '15

hi,I am making a large deposit to the pdb. To convert it to cif i usedphenix.pdb_as_cif model.pdb it looks like the ANISOU lines lose chain information.the PDB responded with this comment "The model coordinates file you output from Phenix is not complete. In the cif format file you deposited, if you look at the cif item _atom_site_anisotrop.pdbx_auth_asym_id, i.e. the column 5 of the Aniso section, you see value for every atom is dot ("."). The _atom_site_anisotrop.pdbx_auth_asym_id is just like the chain ID in the legacy PDB format, it should be consistent with the values of cif item _atom_site.auth_asym_id in the xyz section, otherwise there is no way to map between xyz Cartesian values and aniso values that are now separated in two sections." Do you reccomend another way to convert it to cif ? Thanksjpd

Applications for RapiData 2015 are now open
by Thomas Eriksson 14 Jan '15

14 Jan '15

The 2015 RapiData Course on Data Collection and Structure Solution will take place at the Stanford Synchrotron Radiation Lightsource (SSRL) from May 3-8 2015. The aim of the course is to educate and train scientists in data collection and processing methods at synchrotron beamlines, using state-of-the-art software and instrumentation. The course will comprise hands-on experiments at the SSRL beamlines, software tutorials, and lectures on sample preparation, data collection and reduction, phasing and complementary methods. For a more complete description of the course goals and format see http://www-ssrl.slac.stanford.edu/conferences/rapidata-2015/about.html The deadline for applications is February 23rd 2015. To apply follow this link: http://www-ssrl.slac.stanford.edu/conferences/rapidata-2015/apply.php Several scholarships are available from the International Union of Crystallography to cover partial travel and subsistence for Latin-American students, postdocs and junior faculty. Additional funds may be also be awarded to other participants (no restrictions) on a per need basis. Interested participants should apply for the course, and contact the organizers, enclosing a letter of recommendation from their supervisor. The Organizing Committee of RapiData2015 shall observe the basic policy of non-discrimination and affirms the right and freedom of scientists to associate in international scientific activity without regard to such factors as ethnic origin, religion, citizenship, language, political stance, gender, sex or age, in accordance with the Statutes of the International Council for Science. At this course no barriers will exist which would prevent the participation of bona fide scientists.

Rosetta MR mmcif file subprocess failed
by Christian Roth 13 Jan '15

13 Jan '15

Hi phenix developers, I started a Rosetta MR run with a model pdb and the target sequence file. It seems that the initial MR run went fine and the Rebuilding Job for the best MR solution started. A sequence alignment is shown in the log file and than the job stops suddenly with the message Sorry: mmcif file must contain at least one data block. I can't even find a mmcif file in one of the folders. Any idea what might went wrong. Thanks in advance for your help. Christian

Firth announcement 6th Workshop on Neutron Scattering Applications in Structural Biology Oak Ridge, TN. June 1 - June 5, 2015 Application deadline: April 10, 2015 The workshop on Neutron Scattering Applications in Structural Biology aims at enabling structural biologists to fully exploit the latest instrumentation and software development at the SNS and HFIR facilities at Oak Ridge National Laboratory. Attendees will participate in lectures and tutorials focusing exclusively on neutron techniques applied in structural biology. The workshop is designed for graduate students, post-doctoral fellows and faculty new to or with limited experience of neutron scattering. Travel and accommodation expenses are supported for selected participants from the United States. International applications are welcome. However the course organization is not able to support travel or accommodation. The number of participants will be limited to 15. There is no registration fee for all selected participants. The application package consisting of 1) Information form, 2) CV, 3) Applicant motivation letter (1/2 to 1 page), 4) Principal Investigator letter of support (for graduate students only; 1/2 to 1 page), should be sent electronically to meilleurf(a)ornl.gov<mailto:[email protected]> before April 10, 2015. Detailed information can be found on the workshop web page: https://public.ornl.gov/neutrons/conf/gcnb2015. Flora Meilleur, Ph.

Rw/Rf -phenix - wwPDB Validation Server
by Haytham Wahba 12 Jan '15

12 Jan '15

1- after getting structure refined with phenix.refine to 0.145 , 0.164 Rw/Rf. and then you feel happy with that. then after using validation server from PDB you get 0.158 , 0.181 Rw/Rf. why this big jump for R free. why phenix.refine giving us low R free where in reality is not? 2- if i want to show kick map for metal binding site for publication, which map and how could i generate it. thank you for your help.

A question related to phenix refine
by Dialing Pretty 11 Jan '15

11 Jan '15

Dear All, In a Phenix refinement process, the RMS angles fluctuates between 1.50 and 1.60, i..e., it does not decrease gradually. Can I accept the refinement result or not, and why? I am looking forward to getting a reply from you. Dialing.

how can I merge denzo output files
by lbetts0508 . 11 Jan '15

11 Jan '15

I hope I am a dummy and I missed the obvious, but if I have a list of ".x" files from DENZO integration and want to merge and scale them as an mtz file in phenix or xds (I don't have access to scalepack) is there a pre-written program for that? Laurie Betts

a question related to Phenix and Coot
by Dialing Pretty 11 Jan '15

11 Jan '15

Dear All, When I use WinCoot 0.8.1 to open a PDB file got by Phenix.refine, it comes, Fix Nomenclature Errors. Correct them? Asp [spec: 1 "A" 128 ""]PHE[spec: 1 "A" 134""]PHE [spec: 1 "A" 371""] But when I check the 3 residues, I cannot find any error. Will you let me know the issue? Dialing

A question related to Phaser-MR (simple interface)
by Dialing Pretty 09 Jan '15

09 Jan '15

Dear All, When I run Phaser-MR, I met a fatal error "The composition you have entered has a protein/nucleic acidcontent of 132.513%, which is impossible. DECREASE your composition". Can you remind me in which black I fill the composition? And how to decrease it? Dialing
