Glycan refinement
by Zhou, Tongqing (NIH/VRC) [E] 10 Nov '09

10 Nov '09

Dear All, I am refining a structure with a N-linked glycosylation site. There is density that goes beyond the first NAG, at least to MAN3. I know in Phenix there is data_link = NAG-ASN for the ASN-NAG connection, but I don't know how to do the "apply_cif_link' for the extensions such NAG-NAG, NAG-MAN, MAN-MAN...., any suggestions are appreciated.

Problem reading ".edits" parameter file
by John Pascal 06 Nov '09

06 Nov '09

Hello, On a previous version of PHENIX, 1.4-153, I was able to read in a parameter file with geometry constraints. Upon loading the file, the program asked when to execute the commands, I said at run time, and everything worked fine. Using the same parameter file in PHENIX 1.5-2, I am no longer asked about when to execute the file, and when I proceed to run the refinement, the program quits stating an unexpected character. I can't find anything obviously wrong with the parameter file. Any suggestions? The previous version of PHENIX (the one that worked) is no longer located on my server, so I can't easily return to that version. Thanks.

Phaser question : RMS deviation and FOM
by Peter Grey 06 Nov '09

06 Nov '09

Dear Phenix developers, The expected RMS deviation input to Phaser affects the FOM estimation of phases quality. This in-turn affects the sigmaa weighted maps and most importantly the density modification steps that follow phaser. I would like to ask if, based on the phaser solution and the LLG parameter, one could optimize the RMS estimation or know the real RMS deviation that would result in more true FOM. Thanks, Peter With condolences to the family of Warren DeLano who will be sorely missed

Analyzing MIR datasets

Hi All, I am a new user to Phenix and am trying to process MIR datasets from a parameter file typing 'phenix.autosol mir.eff' and keep running into the error message saying: _______________ Possible choices: /Users/sena/data/crystallography/raw1025/Processing/iafinal_d212121.mtz:I,SIGI,merged /Users/sena/data/crystallography/raw1025/Processing/iafinal_d212121.mtz:IPR,SIGIPR,merged Please use scaling.input.xray_data.obs_labels to specify an unambiguous substring of the target label.

molecular replacement - restricting rotation around a specified orientation
by Christine Gee 06 Nov '09

06 Nov '09

Dear Phenix developers, We have a protein with two sub domains (N-lobe and C-lobe) we are trying to solve by MR. The C-terminal sub domain solves fine (TFZ 11.1), but the N-terminal lobe is not being placed correctly. I read in the online documentation that you can specify a limited rotation range around the orientation you would expect for the N-lobe based on the C-lobe orientation. My question is, how do specify what orientation to start with? I know I need some Euler numbers, but are they just the same ones that the C-lobe writes out with and I use an N- lobe that is basically the other half of the C-lobe pdb (ie the X,Y,Z co-ordinates are consistent with each other at the beginning of the search)? Or do I need to position the N-lobe with the solution C-lobe and write it out for use in the search model, and then how do I specify the Euler? Also we were going to try and use normal mode perturbation to generate an ensemble and I was wondering if there is more documentation somewhere on how to do that? Regards Christine

about Turbo Frodo

Dear all, I have ever used Turbo Frodo as the modelling software in protein crystallography. It is a very convinient software to learn. But it seems that the lience email of turbo is out of work. Does anyone know if Turbo is still maintained by AFMB and the new email for lience?

Running Phenix 1.5.2 with Martin Horvath
by Raghav Kalia 04 Nov '09

04 Nov '09

I recently downloaded and installed phenix 1.5-2. I can launch the GUI by double clicking on the phenix icon. However, I cannot get to run phenix.refine on the command line. How does one set paths so that phenix.refine will be recognized in a terminal window? Raghav Kalia

Elbow ligand building
by Joe Krahn 04 Nov '09

04 Nov '09

I am having some problems building ligand parameters with elbow. I have an accurate reference structure, but elbow seems to "regularize" the coordinates in a way the distorts the structure. Is there a way to disable this? With --opt, QM optimization should hopefully remove distortions, but it is not doing a very good job for this molecule. So, I decided to optimize using Gaussian, and a better basis set. It seems that the Gaussian interface is still fairly simple, and it seems that you have to edit the Gaussian.csh template. So, I did that, but got the "Gaussian does not seem to be installed" message. Unfortunately, elbow runs the Gaussian script with output to /dev/null, so there is no way to see any error messages. Maybe that should be done only when the --quiet flag is given. I edited the Python source to let errors go to the tty, and found that the problem is in the way the script is invoked using "csh -c %s.csh". That only works if "." is in your $PATH, which is often the case. It also invokes an extra instance of csh, because it is invoked as a system command. The correct way to run a shell script is to leave out the '-c'. Elbow makes the script executable, so an even better approach is to just leave out "csh", and do "os.system('./%s.csh' % project)". Then, the script can be in sh/bash/etc. Maybe the was the intent of using '-c'? Thanks, Joe Krahn

re-run jobs in GUI
by Leo Sazanov 04 Nov '09

04 Nov '09

Hi, in a new GUI how can one re-run previous jobs (to make some modifications to them)? If I just try to open parameter (.eff) file from the main file menu in Autobuild, the file does not show up, even though it exists. Just adding it to the list of input files works, but the information is not passed on into GUI? -- Dr. Leonid A.
