Re: [phenixbb] autosol error 1.4-3 when trying to specify deriv.inano=noinano

Hi Francis, Thanks again for the files. They did help me debug the autosol wizard for this case. It turns out that on the command line you cannot say something like, native.data=nat.mtz native.labels="I SIGI" \ deriv.data=deriv.mtz deriv.labels="I+ SIGI+ I- SIGI-" deriv.inano=inano because only the first native.something= gets read, the others are ignored, and similarly only the first deriv.something= gets read. instead all this has to go in a parameters file, and then it all works fine. I have adjusted the wizard to catch this situation and to stop and tell the user that they need to use a parameters file to set more than one parameter in the native, deriv, or wavelength scopes. All the best, Tom T

coordinates and map shifted after phenix.refine without simulated annealing

Hi i am using phenix version 1.4 release tag 70 hari@charlie:~$ phenix.refine --version ------------------------------------------------------------------------------- PHENIX: Python-based Hierarchical ENvironment for Integrated Xtallography Version: 1.4 Release tag: 70 Platform: intel-linux-2.6-x86_64 linux User: hari ------------------------------------------------------------------------------- I am seeing a strange shifting of my coordinates "out of my experimental phases map" before and after refinement without simulated annelaing I am at the final stages of my refinement. When I refine without simulated annealing the resulting model is shifted relative to my experimental phases map into which I build my model The phenix command line strategy i am using are rigid_body+individual_sites+individual_adp+tls .or the same strategy with simulated_annealing=true The output map coefficients fortunately match my model in both cases . But I am wondering why there is a difference. I am using the mlhl target for refinement to 3.1 A , My R and rfree is 28/31 . Any ideas why my model shifts without simulated annealing . All pdbs have the same CRYST record . I am using coot version 0.61 for my building and map display using fft inside of coot . hari

Re: [phenixbb] coordinates and map shifted after phenix.refine without simulated annealing
by Thomas C. Terwilliger 06 Jun '09

Hi Hari, What is your space group? I am guessing that the shift is along an axis where the origin is not fixed, for example the b axis in P21. This could happen with rigid-body refinement where a molecule can move as a whole so that the center of mass could move along that axis. Perhaps someone else can comment as to whether there is or could be an optional term in phenix.refine to maintain the center of mass at the same coordinate in such cases.

Parallel Version of Phenix?
by Angelo Rossi 03 Jun '09

03 Jun '09

Hello Phenix Users and Developers: I am new to Phenix and am trying to help a colleague move his project using Phenix from a single workstation to a Linux cluster. My background is chemistry and high performance computing, but I am not intimately knowledgeable about the workings of Phenix. Are there parts of Phenix that can run on a Linux cluster in parallel. I understand that a good part of Phenix is written in python, but there are certainly numerically intensive aspects of structure refinement that could be amenable to parallelization. It would really help if you could provide an overview of those components that are now running in parallel. A search on the net did not reveal information about a parallel version of Phenix. Thank you for your attention and any possible help. Kind regards, A. R. Rossi

Fixing coordinates in phenix.refine_gui
by AMIT 02 Jun '09

Hi All Is it possible to fix only the coordinates(xyz's) of residues or individual atoms in phenix.refine_gui while refining it for rest of the atoms? Any suggestions will be helpful.

Is there an option or a phenix.* utility to mutate a MR model to poly ALA before the MR is done? Thanks!

covalently linked ligand
by Joerg Standfuss 27 May '09

27 May '09

Dear phenix users, I am currently building a model where the ligand is linked via schiff base to a lysine residue. To let phenix know about the link I provide the ligand.cif file and created the link parameter file as described in the manual. The type of link I defined with Jligand as it does not appear in the standard ccp4 library. Unfortunately phenix.refine stops with the error message below when I provide the so created files. It seems phenix has problems to apply the needed ligand modifications ie removing hydrogens and oxygens and stops with the refinement. I have no idea why this doesn't work and am getting a little desperate so any suggestions how to do this properly would be greatly appreciated. Could I use for example elBOW to create the link description? many thanks, Joerg File "/lmb/home/public/xtal/Phenix/phenix-1.4-3/mmtbx/ monomer_library/pdb_interpretation.py", line 499, in __init__ mod_mod_id=self.mon_lib_srv.mod_mod_id_dict[apply_data_mod]) File "/lmb/home/public/xtal/Phenix/phenix-1.4-3/mmtbx/ monomer_library/pdb_interpretation.py", line 771, in apply_mod mod_mon = self.monomer.apply_mod(mod_mod_id) File "/lmb/home/public/xtal/Phenix/phenix-1.4-3/mmtbx/ monomer_library/cif_types.py", line 339, in apply_mod result.delete_atom_in_place(mod_atom.atom_id) File "/lmb/home/public/xtal/Phenix/phenix-1.4-3/mmtbx/ monomer_library/cif_types.py", line 244, in delete_atom_in_place raise RuntimeError("delete_atom_in_place: unknown atom_id: %s" % atom_id) RuntimeError: delete_atom_in_place: unknown atom_id: H151
