phenix.pdb_as_cif
by jp d 14 Jan '15

14 Jan '15

hi,of course, i should have included the versionphenix.version_1.9-1692 the pdb has done more digging and included this comment "Aside from the asym_id, there is another way we use for the mapping, _atom_site_anisotrop.id should map(for ANSIO) to _atom_site.id(for ATOM). This is one-by-one match for each atom. If you look at the file, you see that in the ATOM section, you have ATOM 99999 N3 . U . 367 ? -23.56200 29.36600 106.68800 1.000 135.52000 N ? UC ? 11964 1 ATOM 100000 C4 . U . 367 ? -23.35700 30.62600 106.16100 1.000 133.22000 C ? UC ? 11964 1 But in the ANISO section, you have 99999 N3 . U . 367 ? 2.04230 1.43260 1.67410 -0.19220 -0.28280 -0.16500 A0000 C4 . U . 367 ? 2.00150 1.41600 1.64420 -0.1 8730 -0.28010 -0.16450 i.e. the atom No. after 99999 is inconsistent between the two sections. The ANISO should use 100000. " thanksjpd

Importing project to Phenix
by Emilia C. Arturo (Emily) 14 Jan '15

14 Jan '15

Hello, I'd like to take a phenix project (on which I've been working successfully on the Mac where I initially created the project) from one Mac to another Mac. When I tried to use the 'Import project' tool on the new computer, I got a notification that "[...] the directory must contain the PHENIX project tracking data (a sub-directory named 'phenix' or '.phenix', and associated files)." Unfortunately, I didn't see a sub-directory named 'phenix' or '.phenix' in the folder where all my project files had been created and stored, and wasn't sure what to do about it, so I proceeded with the Import anyway, to see what would happen. On the new computer, the project was imported seemingly successfully (e.g. the project history is all there), but when I tried to Run a refinement I'd configured for this project, I got an error about the missing '.phenix' file. The error is: "Cannot open file for write: [...] No such file or directory: [...]/.phenix/project_data/refine_22.eff' Can someone help me figure out how to properly move a project from one computer to another? Thank you, Emily.

pdb_as_cif
by jp d 14 Jan '15

14 Jan '15

hi,I am making a large deposit to the pdb. To convert it to cif i usedphenix.pdb_as_cif model.pdb it looks like the ANISOU lines lose chain information.the PDB responded with this comment "The model coordinates file you output from Phenix is not complete. In the cif format file you deposited, if you look at the cif item _atom_site_anisotrop.pdbx_auth_asym_id, i.e. the column 5 of the Aniso section, you see value for every atom is dot ("."). The _atom_site_anisotrop.pdbx_auth_asym_id is just like the chain ID in the legacy PDB format, it should be consistent with the values of cif item _atom_site.auth_asym_id in the xyz section, otherwise there is no way to map between xyz Cartesian values and aniso values that are now separated in two sections." Do you reccomend another way to convert it to cif ? Thanksjpd

Rosetta MR mmcif file subprocess failed
by Christian Roth 12 Jan '15

12 Jan '15

Hi phenix developers, I started a Rosetta MR run with a model pdb and the target sequence file. It seems that the initial MR run went fine and the Rebuilding Job for the best MR solution started. A sequence alignment is shown in the log file and than the job stops suddenly with the message Sorry: mmcif file must contain at least one data block. I can't even find a mmcif file in one of the folders. Any idea what might went wrong. Thanks in advance for your help. Christian

1- after getting structure refined with phenix.refine to 0.145 , 0.164 Rw/Rf. and then you feel happy with that. then after using validation server from PDB you get 0.158 , 0.181 Rw/Rf. why this big jump for R free. why phenix.refine giving us low R free where in reality is not? 2- if i want to show kick map for metal binding site for publication, which map and how could i generate it. thank you for your help.

A question related to phenix refine
by Dialing Pretty 11 Jan '15

11 Jan '15

Dear All, In a Phenix refinement process, the RMS angles fluctuates between 1.50 and 1.60, i..e., it does not decrease gradually. Can I accept the refinement result or not, and why? I am looking forward to getting a reply from you. Dialing.

I hope I am a dummy and I missed the obvious, but if I have a list of ".x" files from DENZO integration and want to merge and scale them as an mtz file in phenix or xds (I don't have access to scalepack) is there a pre-written program for that? Laurie Betts

advice on 'Fit rotatable H or D' refinement stage in phenix.refine
by Anna Makal 07 Jan '15

07 Jan '15

Hi, I would like to ask for advice concerning 'Fit rotatable H or D' refinement stage in phenix.refine. I am attempting to run unconstrained refinement on a certain high-resolution protein dataset: just XYZ and ADPs refinement for every single atom in the structure, with hydrogen atoms treated with individual approach. It turns out that when I set more then 3 macrocycles, the 'Fit rotatable H or D' refinement stage is activated in every macrocycle prior to 'XYZ individual' refinement stage. I am using version 1.9, release 1692 for windows. When I last worked with PHENIX, it was distribution 1342, and I am positive I have not come across such refinement stage. It seems that TARDY is involved at that stage. As I specifically do not want to introduce any kind of torsion angle dynamics in my current refinement, I would like to ask, what command/option shall I use to deactivate this stage of H-atom fitting in my refinement? With regards, Anna Makal

Coot failed to launch in Phenix after CCP4 update

Dear all, After I updated ccp4 to a new version (ccp4-6.5), I found that coot failed to launch in phenix. /Applications/PHENIX-1.9-1692/Contents/phenix-1.9-1692/build/mac-intel-osx-x86_64/../../phenix/phenix/command_line/start_coot.sh: line 37: /Applications/ccp4-6.4.0/coot.app/Contents/MacOS/coot: No such file or directory Apparently it requires ccp4-6.4.0, which has been deleted. I tried to modify find_coot_command.py in phenix, but it didn’t work. Can anybody give me some suggestions so that I can figure this problem out? Thanks! Best, Shun

Dear All, when using FEM maps I notice that some solvent structure has clean (ish) 2Fo-Fc but not FEM density. Is this indicative of the water without FEM density being simply noise or is it more complicated than that? Many thanks, Colin Manchester Protein Structure Facility Dr. Colin W.

I mean by all the documents saved automatically by the Phenix.refine after it finished a refinement, how can I get the Phenix refine window once more, for the check of Log output, Run status, Results, MolProbity, Real-space correlation, Atomic properties, and sequence check?

Cross-validation when test set is miniscule
by Derek Logan 19 Dec '14

19 Dec '14

Hi everyone, Right now we have one of those very difficult Rfree situations where it's impossible to generate a single meaningful Rfree set. Since we're in a bit of a hurry with this structure it would be good if someone could point me in the right direction. We have crystals with 1542 non-H atoms in the asymmetric unit that diffract to only 3.6 Å in P65, which gives us a whopping 2300 reflections in total. 5% of this is only about 100 reflections. Luckily the protein is only a single point mutation of a wild type that has been solved to much better resolution, so we know what it should look like and I simply want to investigate the effect of different levels of conservatism in the refinement, e.g. NCS in xyz and B, group B-factors, reference model, Ramachandran restraints etc. However since the quality criterion for this is Rfree I'm not able to do this. I believe the correct approach is k-fold statistical cross-validation, but can someone remind me of the correct way to do this? I've done a bit of Googling without finding anything very helpful. Thanks Derek ________________________________________________________________________ Derek Logan tel: +46 46 222 1443 Associate Professor mob: +46 76 8585 707 Dept. of Biochemistry and Structural Biology www.cmps.lu.se<http://www.cmps.lu.se> Centre for Molecular Protein Science www.maxlab.lu.se/crystal Lund University, Box 124, 221 00 Lund, Sweden www.saromics.com
