Can I run Phenix with a .fcf file and a .pdb file? If not how can I convert .fcf to the correct format? Rex Palmer http://www.bbk.ac.uk/biology/our-staff/emeritus-staff http://rexpalmer2010.homestead.com

Run PHENIX commands on GUI verison?
by 李翔 10 Jun '14

10 Jun '14

Hi, I currently can only access to PHENIX with my laptop which has a Windows system (GUI). I want to run some commands for generating restraints for my models such as: iotbx.show_distances MR.1.pdb > contacts.distances, phenix.secondary_structure_restraints model.pdb Is there a way I can run commands in GUI version or can I run the above commands in the GUI version? Thanks for your help! Sincerely, Xiang -- Li Xiang Department of chemistry, Purdue University Email：lixiang1642(a)gmail.com

B-factors for some sidechains were not refined well
by Zhou, Tongqing (NIH/VRC) [E] 09 Jun '14

09 Jun '14

Dear colleagues, I am refining one structure at 1.94 A with phenix.refine with individual b, TLS, and xyz. The Rwork and Rfree are now at 16.1 and 19.8%. But when inspecting the maps, I noticed that the sidechain tip of some residues showed positive density and the b-factor for those atoms were very high while those for the other atoms of the same residues were normal; The b-factors for newly added ligands were also not refined well showing high b-value and positive density at the same time; the disulfide bonds also show positive density and high B. The occupancy were all set to 1. Please give suggestions. Thanks!

launching MR jobs from the command line.
by Francis Reyes 05 Jun '14

05 Jun '14

Hi all, For the moment (1.9-1692) phenix.automr still works from the command line but I received a note that it's a 'Deprecated program' . ************************************************************************ WARNING - DEPRECATED PROGRAM Please note: the command-line AutoMR tool and associated GUI have been deprecated and will be removed in future releases. We recommend that you use phenix.mrage or phenix.phaser, both of which are available in the GUI. The program will resume execution in 5 seconds. ************************************************************************ phenix.mrage doesn't resolve to anything, and phenix.phaser runs the phaser binary. Is there a new way to launch MR jobs from the command line (which had all the PHIL friendly goodies that automr had?) ? Thanks, F

difference map peak in coot not showing all peaks?
by Murpholino Peligro 05 Jun '14

05 Jun '14

In coot I have set the map contour level to 5.0 rmsd and I do Validate -> Difference Map Peaks ... and the new window shows me where the peaks are...but not all of them. For example, see screenshot attached. (there are peaks above sg cys80 and sg cy64, both appear in the visual window in coot but only one of them, cys80, in the listing. If I understand clearly, they should both appear in the visual window and in the listing because I have the same filter (5.0 rmsd). Right? Now...the peaks values are from Phenix doing a Isomorphous Difference Map ... So I do not know if this is from Coot or from Phenix.

Autosol and sequence file
by Stefan Knight 03 Jun '14

03 Jun '14

I don’t seem to have much luck with Phenix these days… Trying to run Autosol from the GUI but the process aborts immediately complaining that a sequence file is required to run Autosol. I have given it a sequence file in fasta format that is recognised as such when added. I’ve also tried instead pasting the sequence into the Crystal info window but that didn’t help. Grateful for any tip on how to convince Phenix it has all it needs to get going ;-).

How to add difference map peak value to B-factor column in Phenix-Coot after isomorphous difference map?
by Murpholino Peligro 02 Jun '14

02 Jun '14

Hi all. How to add a difference map peak value to B-factor column in Phenix-Coot after isomorphous difference map? Because what I get (after Phenix Isomorphous Difference Map) is a pdb with the peaks (chain A) and holes (chain B) with their positions given by UNKnown atoms, 1 for occupancy and in the B-column their peak-or-hole value. I would be happy if I could get the actual atoms with positions and the peak-or-hole value in the B-column. Thanks again and again.

molecular replacement keeping hetatms?
by Murpholino Peligro 28 May '14

28 May '14

Can I do molecular replacement with phenix/phaser, keeping all the waters from the first model from the first data set? >From here ( http://www.phaser.cimr.cam.ac.uk/index.php/Molecular_Replacement#WATER), I should change all the HOH labels to something like WWW. Then I guess that I should put HOH labels again in the solution model, for the following refinement in phenix.refine. Is that it?... Any suggestions? thanks again!
