bgroup refinement of ZN ions
by Ursula Schulze-Gahmen 13 Nov '17

13 Nov '17

I have 2 Zn ions which are defined as HETATM, in my structure. I am using tls and bgroup refinement for the whole structure. It seems like the Zn ions are treated as one group. They always have the same B-value. I would like to refine the B-value of the ZN ions separately, but refine the rest of the structure with bgroup refinement. Is that possible? How would I do this?

mmtbx.prepare_pdb_deposition sequence file
by Ursula Schulze-Gahmen 09 Nov '17

09 Nov '17

I have problems running 'mmtbx.prepare_pdb_deposition' on the cif file created in phenix. I think the problem may be the sequence file. The coordinates are from a complex of 4 proteins plus an RNA. I created a text file with 5 chains, each chain sequence in one letter code. I am getting the following error code when I try to run the program: Traceback (most recent call last): File "/home/programs/x86_64-linux/phenix/1.12-2829/phenix-1.12-2829/build/../modules/cctbx_project/mmtbx/command_line/prepare_pdb_deposition.py", line 99, in <module> run(sys.argv[1:]) File "/home/programs/x86_64-linux/phenix/1.12-2829/phenix-1.12-2829/build/../modules/cctbx_project/mmtbx/command_line/prepare_pdb_deposition.py", line 69, in run alignment_params=params) File "/home/programs/x86_64-linux/phenix/1.12-2829/phenix-1.12-2829/modules/cctbx_project/iotbx/pdb/hierarchy.py", line 1052, in as_cif_block_with_sequence assert len(chain.residue_groups) + chain.n_missing_start + chain.n_missing_end == len(sequence) There seems to be something wrong with chain N, but I am not sure what. Is it ok to have a longer sequence in the sequence file than in the coordinates?

chain and residue ID in phenix.erraser
by Ursula Schulze-Gahmen 08 Nov '17

08 Nov '17

I am trying to run phenix.erraser, but I am not able to define the single residue for rebuilding correctly. I am getting error messaheg: Please make sure that you include both the chain ID and residue number, for example 'A15'. I want to rebuild nucleotide G32 in chain N, and defined the residue as N32. That is not correct. What would be the correct syntax for this case?

kicked map calculations
by Ursula Schulze-Gahmen 07 Nov '17

07 Nov '17

I am trying to calculate kicked maps in the phenix GUI, but I don't get the option, nit in the mtz files, and not in the CCP4 map option. Could that have something to do with this error message I am getting when starting Phenix: Gtk-Message: Failed to load module "canberra-gtk-module" Gtk-Message: Failed to load module "pk-gtk-module" Or are there any settings I need to change?

data fill in in phenix refine?
by Ursula Schulze-Gahmen 26 Oct '17

26 Oct '17

I have data from a crystal with anisotropic diffraction. After scaling and merging using the webserver staraniso, I would like to refine using phenix refine. Could you tell me if phenixrefine will try to fill in the missing reflections that were removed in the staraniso procedure? If so, is there a a way to prevent this fill in? Following is the warning message for the Staraniso server: We are grateful to Andrew Leslie (MRC-LMB) for identifying a potentially undesirable 'feature' of CCP4/REFMAC (and possibly other refinement software), namely the 'fill-in' of unobserved data with *DF*calc which makes it effectively *incompatible* with the MTZ file output by STARANISO. Our advice is therefore to use *BUSTER <http://www.globalphasing.com/buster>* for refinement using the downloaded MTZ file, unless the user can find a way to disable that feature in the alternative software. In general, any treatment of STARANISO's output data that adds missing reflections out to the resolution limit may result in a very high proportion of unobserved data compared with data that have had a cut-off applied according to an isotropic criterion. Where missing reflections have been added in this way the user should take care to verify that any applications used to process the data subsequently can handle it correctly.

Announcing the release of CryoFIT
by Nigel Moriarty 23 Oct '17

23 Oct '17

Dear colleagues, We are excited to announce the release of CryoFIT, a program for fitting atomistic models to cryo-EM maps. The current version is designed for fitting lower resolution maps but this does not preclude use with higher resolution maps. The CryoFIT modules is built on Gromacs and accessible through Phenix (https://www.phenix-online.org/documentation/reference/ cryo_fit.html), currently via GitHub. It supports both the Phenix GUI and the command line. CryoFIT is based on the algorithm in Kirmiziatltin, et al., Methods of Enzymology 2015 (https://doi.org/10.1016/bs.mie.2015.02.011). This is an alpha version. Please send any feature requests and bug reports to Doo Nam Kim (doonam(a)lanl.gov). Happy Modeling! Cheers Nigel --- Nigel W.

Hi all, Is anyone still using "allsvn" from the phenix_regression repository? If not, we'll just delete it next Friday (10/27) since it's hopelessly out of date.
