reflections file editor
by Almudena Ponce Salvatierra 14 Apr '15

14 Apr '15

Dear all, I would like to merge two datasets containing anomalous signal. If have done so earlier for native data within phenix in the reflections editor by selecting the arrays corresponding to FP and SIGFP and then running the program. However when I try to do so for the anomalous datasets it writes FP SIGFP and FP2 SIGFP2 instead or merging them, so it does with the anomalous signal... so I guess I have basically only one file containing two datasets but not a merged dataset. How can I solve it? Would it be possible, on the other hand, to merge a dataset with anomalous signal with a native one? The intention behind is to extend the resolution to the one of the native data.

sugar puckering refinement with phenix refine
by Almudena Ponce Salvatierra 13 Apr '15

13 Apr '15

Dear all, does anyone know how phenix.refine deals with the sugar puckering of an RNA or a DNA strand? Does it refine it? Or does it leave it as it was built? Thank you very much in advance. Best wishes, Almudena -- Almudena Ponce-Salvatierra Macromolecular crystallography and Nucleic acid chemistry Max Planck Institute for Biophysical Chemistry Am Fassberg 11 37077 Göttingen Germany

Link NGA and THR
by Cory Brooks 13 Apr '15

13 Apr '15

Hello! I am refining a structure with O-link glycosylation (GalNAc linked to Thr). Phenix seems to remove the link during refinement. Can anyone suggest a solution that will maintain the bond during refinement? Regards, Cory Cory Brooks,Ph.D.

pdbtools: how to set the occupancy for an atom selection?
by Alejandro Virrueta 13 Apr '15

13 Apr '15

Hello, I was wondering if someone could show me a way to set the occupancy of a specific set of atoms to 0 using phenix.pdbtools. I noticed here <http://www.phenix-online.org/download/documentation/cci_apps/pdbtools.html#…> that there is no option under modify => occupancies to do an 'atom_selection'. Any help would be appreciated. Cheers, Alex

Deposition question
by mohamed noor 13 Apr '15

13 Apr '15

Dear all I solved my structure using SAD from heme to 2 A and then did molecular replacement with a dataset diffracting to 1.2 A. Do I deposit only the mtz and pdb file from the last refinement run and report the corresponding statistics in 'Table 1'? Should I specify the experimental f' and f'' values? Thanks.

expermiental sigma or SIGFP of the mtz file
by Smith Lee 13 Apr '15

Dear All, Will you please let me know what is the expermiental sigma or SIGFP of the mtz file? If a mtz file lacks the expermiental sigma or SIGFP, what does it mean? I am looking forward to getting your reply. Smith

Reference model restraints in real space refinement?
by Oliver Clarke 12 Apr '15

12 Apr '15

Hi all, Is it possible to use reference model restraints at the moment during real space refinement (in phenix.real_space_refine)? I can’t see it in the documentation. On a related note, would it be possible at some point to allow users to set d_max in the phenix.map_to_structure_factors utility? At the moment it seems like the user can set d_min but not d_max - sometimes it is convenient to restrict the low res to 20 or 50Å, rather than the whole box size of an EM-map, which is the default. Best, Oliver.
