Hi lads... Do you know if there is a good tutorial for doing RIP somewhere on the internet? What programs can do RIP? -SHELX -AutoRickShaw -? Thanks

Can I use PHENIX "Find NCS" tool to verify space group ?
by Alex Lee 23 Apr '17

23 Apr '17

Hi All, I have a protein/dna dataset (3A resolution) with space group (SG) ambiguity, it could be P32 with two copies of molecules (one copy of molecule composed of protein homodimer with asymmetric dsDNA) in asymmetric unit (ASU) or P3221 with one copy of molecule in ASU. Both SG can give me MR solutions and after Refmac P32 Rfree is around 31% while P3221 Rfree is around 34% (without any twin refine at this stage). Density maps from both SG makes sense and they are similar by eye inspection. Because of partial twinning of the dataset (estimation twin fraction alpha around 0.22) , which confuse programs of assigning the correct SG. Pointless and Xtriage suggests P6222, which we are sure it's not correct (based on performance on both MR, Refmac and biology sense that dsDNA is asymmetric, and if P6222 is true then based on Mathew coef. there will be a monomer protein with single strand ssDNA in ASU). Zanuda suggests SG P32 in both cases (input experimental data P32 or P3221 along with refined model). However, Zanuda may not work well in twin case. In short, the problem now is to choose one SG from P32 or P3221. There is one suggestion that try SG P32, as there are two copies of molecules in ASU in P32 group, try find the NCS operator in P32 and check if this operator is close to crystallographic symmetry operator or not, if it is, then SG is P3221, if it's not, then SG is P32. I did a few rounds of search in Internet, I found Phenix "Find NCS tool" and input PDB of my refined structures from both P32 and P3221. For both test, Find NCS tool did find NCS operator but in the end of the log file I see the same results as below: This NCS object does not contain point group symmetry This NCS object does not contain helical symmetry. I am asking: 1. does "This NCS object does not contain point group symmetry" from Find NCS tool mean that NCS operator in my PDB is not crystallographic symmetry operator? 2. Is there a tool in Phenix which can find the NCS operator and check if the NCS operator is close to crystallographic symmetry operator or not? Thanks ahead.

Cannot compile rosetta interface Centos 7 with 1.11.1
by ludovic Pecqueur 21 Apr '17

21 Apr '17

Dear Phenix developers, I installed the latest phenix version today (1.11.1-2575) on Centos 7.2 I have rosetta_2016.13.58602 When I try to compile the rosetta interface (after exporting PHENIX_ROSETTA_PATH), compilation fails (see end of message for errors). When I compile the rosetta interface using phenix 1.11-2567, compilation goes to completion without errors. If you have any idea of the change between the two versions leading to this issue.

Generate a map showing local agreement between map and model
by #AHMED TOFAYEL# 18 Apr '17

18 Apr '17

Dear developers and users, Is it possible to generate a map to show local agreement between cryo-EM map and the model generated using the same map? If I am not wrong, the supplementary figure S5 had accomplished the job (using Chimera), but I don't understand how to generate a similar figure for my project. Is it possible to do with phenix? http://emboj.embopress.org/content/28/6/755 Best regards, Tofayel NTU Singapore

All details can be found at http://www.ccp4.ac.uk/schools/APS-2017/index.php Dates: June 19 through 26, 2017 Site: Advanced Photon Source, Argonne National Laboratory, Argonne (Near Chicago), Illinois, USA The school comprises Data collection workshop: beamline training; data collection on GM/CA@APS beamlines 23ID-D and 23ID-B equipped with Pilatus3 6M and Eiger 16M detectors, respectively; and data processing. For data collection, only the participants' crystals will be used. Crystallographic computation workshop: will feature many modern crystallographic software packages taught by authors and other experts. The daily schedule will be organized in three sections – lectures, tutorials, and hands-on, interactive trouble-shooting of the technical difficulties the participants face in their projects. We have had considerable success resolving these problems in past years, attested by resulting publications http://www.ccp4.ac.uk/schools/APS-school/publications.php Applicants: Graduate students, postdoctoral researchers and young scientists at the assistant professor level, along with commercial/industrial researchers are encouraged to apply. Only 20 applicants will be selected for participation. Participants of the workshop are strongly encouraged to bring their own problem data sets or crystals so the problems can be addressed during data collection and/or computation workshops. Application: Application deadline is April 19. The application form, the program, contact info and other details can be found at http://www.ccp4.ac.uk/schools/APS-2017/index.php Registration fees: The registration for application is free but there is $500 participation fee for the selected academic students and $950 for the industrial researchers. The link for the on-line payments and instructions will be provided once the selection process is completed. The students will be responsible for their transportation, lodging and breakfast. The workshop organizers can assist in making the reservations at economical lodging at the Argonne Guest House. The workshop will cover all other expenses. We hope to see you at the school.

Refinement of two co-factors at the same position
by Kornelius Zeth 12 Apr '17

12 Apr '17

Dear all, I'm trying to refine the occupancy and position of two co-factors iron (III) and FEO (Fe-O-Fe) in a crystal structure. The iron (III) is placed with some occupancy on one of the iron positions in FEO. If I refine them together in Phenix with low occ phenix.refine moves the atoms apart. What is the best way of dealing with this problem? Thanks and best wishes Kornelius
