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

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.

Error refining with ramachandran restraints
by Oliver Clarke 10 Apr '15

10 Apr '15

Hi all, When I attempt to run a refinement using phenix.refine from the command line, using the parameter “ramachandran_restraints=true”, in the latest nightly build of phenix (dev-2006), I get the following error: ========================== Anomalous scatterer groups ========================= All atoms refined with f_prime=0 and f_double_prime=0. Traceback (most recent call last): File "/Applications/phenix-dev-2006/build/../modules/phenix/phenix/command_line/refine.py", line 11, in <module> command_line.run(command_name="phenix.refine", args=sys.argv[1:]) File "/Applications/phenix-dev-2006/modules/phenix/phenix/refinement/command_line.py", line 96, in run master_params=customized_master_params) File "/Applications/phenix-dev-2006/modules/phenix/phenix/refinement/driver.py", line 272, in __init__ secondary_structure_manager=self.sec_str, AttributeError: refine instance has no attribute 'sec_str' This happens for two different structures, so I don’t think it is a structure-specific thing, and I don’t recall this happening in older builds of phenix. The refinement runs fine if I don’t specify ramachandran restraints. Is there something obvious I am doing wrong? Best, Oliver.

Autobuild error
by Lau Sze Yi (SIgN) 08 Apr '15

08 Apr '15

Hi, I did an Autobuild run. The Status panel indicated that the run is finished. In the Model building panel the status of run# 5 still says running (See attached screenshot). Is this normal? And when I click on run #4 to Open in Coot, I get an error message indicating that the directory could not be found (see attachment). What is wrong and how can I fix this? I am using version phenix-1.9-1692 on Mac.
