Phaser with fixed solution
by Ursula Schulze-Gahmen 30 Jan '13

30 Jan '13

I am trying to solve a structure by molecular replacement in phaser using 2 model fragments. I think I may have placed the 1st fragment correctly. I don't quite understand how to best proceed with a fixed ensemble searching for the second fragment in phaser-MR. If I select "use partial solution from previous job", do I still need to read in the coordinates of that previous solution for one ensemble? And If I do, should I read in the starting coordinates or the placed output from this 1st molecular replacement? The second question is about how to relax the restraints fr the packing. In the "other settings" sub window is a section for packing. Could someone explain to me what the different options in this packing section mean? Which of them should I change to allow for more close contacts? Thanks Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

Re: [phenixbb] Unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 bits

I just installed yesterday the latest nightly build on our Scientific Linux 6 (6.3, I believe) machine using the 64-bit FC3 installer. No problems.

To be honest I simply don't understand library versioning issues - the Fedora 3 machine we build that installer on currently has glibc 2.3, so I don't know where the GLIBC_2.14 is coming from. I think it will be significantly more work to figure out a workaround than trying the other installers, though. Unfortunately we do not actually have a Scientific Linux system here - the closest I could find was CentOS 6.2, and that works okay. -Nat _______________________________________________ phenixbb mailing list phenixbb(a)phenix-online.org http://phenix-online.org/mailman/listinfo/phenixbb

Re: [phenixbb] Unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 bits
by Kay Diederichs 29 Jan '13

Davi, This looks to me like you tried installation using e.g. the fc14 installer (that has a glibc "too new" for SL6), and installed with the fc3 on top of that (SL6 works well with the fc13 or lower installer). Since the installers write to the same directory, the fc3 installer finds that the files are already there and does basically nothing that would fix the problem, i.e. replace the binaries and libs. So just remove the /usr/local/phenix-1.8.1-1168 directory (or its contents) before you try a different installer. (Side note: maybe the installer should do that automatically, but there are probably reasons why it doesn't) HTH, Kay On 01/29/2013 12:31 AM, phenixbb-request(a)phenix-online.org wrote: > Message: 5 > Date: Fri, 25 Jan 2013 16:15:01 -0800 > From: Davi de Miranda Fonseca<davi.fonseca(a)ntnu.no> > To: phenixbb(a)phenix-online.org > Subject: [phenixbb] Unable to install phenix 1.8.1-1168 on Scientific > Linux 6.3 64 bits > Message-ID:<51032005.9040800(a)ntnu.no> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > Dear all, > > I am unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 > bits.

Add restraints between base-pairs in GUI & structures comparison
by Xiang Li 28 Jan '13

28 Jan '13

Hi everyone, I am a new user of Phenix and have a few questions asking for help. 1 I worked on a DNA structure and wanted to add restraints during the refinement. I used GUI version and chose "secondary structure restraints"->"restraint base pairs". However, there were some distortion of the base pairing after refinement. Is there a way to assign the base pairing between specific base pairs and force the base pairings in the GUI version? 2 I want to compare two DNA structures to see the RMSD. Each of them were composed of 4 strands. Seems "structure comparison" software can not work with such multiple strands DNA structures. Do you have any suggestions on how to do the comparison please? Thank you very much for your reply! Sincerely, Xiang

multiple occupancy
by Damian Niegowski 28 Jan '13

28 Jan '13

Hi all, I´m trying to refine a dataset which seems to have two different ligands with partial occupancy in the same active site. How do you refine this? When I put them over each other with say 50/50 occupancy Phenix either moves the ligands apart or mashes the two molecules into one strange composite ligand. In Refmac this works without any special settings, it accepts the occupancy distribution between the ligands. Any ideas?

So we have extended the standard registration fee once more to Tuesday, Jan 29th. As we have to submit our room list Feb 1 to get the room rates at discount, this has to be the last extension. Of note, the meeting is 'all inclusive' - registration includes the meeting, lodging, and all meals (breakfast, lunch and dinner, coffee breaks, and social hours). That said, WCPCW21 is quite full, but we can accommodate a few more. In addition, we have not yet started to select posters for oral presentations. So it is still possible, especially for graduate students and postdocs, to give an oral presentation. Look forward to meeting every one in Monterey! Best, John
