TEXTAL Model from map
by Andrzej LYSKOWSKI 09 May '06

09 May '06

Hi, I have one question and one problem. TEXTAL expects map in X-PLOR format but what kind of map? One can make a number of different maps in CCP4 (simple, mFo-nFc, etc.). Which type make TEXTAL happy? I've tried to run 'Build Complete Model from map' strategy and what ever I do it seems to get stuck at: Stitching and Filtering C-alpha chains... - simply nothing happens anymore. What could be a problem? Just to mention it does build a model when I use '... from mtz' strategy.

Judging AutoSol Output
by agb838＠mail.usask.ca 30 Apr '06

30 Apr '06

I have some basic questions about the output from Phenix. Basically I have a data set that gave a solution, but I am not exactly sure how to tell about the quality of the solution from the outputs. The overall score is 110. I am not sure exactly what that refers to or how good/bad it is. I have attached the AutoSol.output file. Any basic suggestions at what I should be looking at, or if this is even the right file, would be helpful. The resolve.mtz and resolve.pdb look alright. They are a good start, but much improvement is needed. If anyone has some suggestions as to how to improve the output, that would also be helpful. I have also run the data through solve/resolve through the command prompt and it repeatedly locates four heavy atom sites (the data set is SAD). Yet, when Phenix is used, 16 sites are found. Why the difference and how do I tell what is working better and why. Thank you, Angela Hoffort

Juding from your output, it find most sites in 1 go. If you want to compare sites you find by Solve, Hyss, or famous programs from Buffalo or Goettingen, use iotbx.emma ha_from_autosol.pdb other.pdb To get an idea how many sites are matching. As far as I understand it, the overall score is a score relative to the other hand and other solutions and its absolute value is not so important, as long as it is (much) larger that any other solution. In your case, solution 1 has a score of 110, solution has a solution of 63. It is also finding NCS, which seems to be good (NCS correlation of 0.66 early no allready). Improvement of the pdb file is obtained by runnnig the modelbuild wizard I think. The Autosol wizard only carries out a limit number of model building cycles and the modelbuild wizard does a more thorough job.

phenix.refine Crashes with "ZeroDivisionError: float division"
by Dale Tronrud 14 Apr '06

14 Apr '06

Hi, I'm new to phenix and phenix.refine. I am trying to refine a protein with phenix.refine but the program crashes quite quickly. I have appended all of the output below, but the critical part is (I believe): File "/usr/local/phenix-1.1a/cctbx/cctbx/miller.py", line 432, in auto_anomalous anomalous_flag = (2*self.n_bijvoet_pairs()/self.indices().size() ZeroDivisionError: float division Apparently, self.indices().size() is zero, but I don't know why or really what that is. My mtz file does not contain any anomalous data. It just has F, SigF, and a free R flag for the positive octant of data. (Well, since this is P6122 the positive duodecant.) Any advise would be appreciated.

Passing keyword to a Wizard

Hi, I'm getting a feedback from AutoBuild Wizard that I should set it with coarse_grid keyword (info from LAST.LOG). However, this keyword isn't present in Set Variable menu. How can set it?

> > Another thing is i installed in a user so whenever i do project it > gives permission denied . I suspect you have the following situation: drwx------ 2 rwgk cci 4096 Mar 14 10:47 phenix-1.1a I.e. when you installed phenix the "umask" was set such that "group" and/or "others" don't have read permission. Please verify my suspicion with ls -d $PHENIX If you see the "drwx------" or maybe "drwxr-x---" it is easy to fix. Use the su command to become root, then: find phenix-1.1a -exec chmod go+r {} \; find phenix-1.1a -type d -exec chmod go+x {} \; Cheers, Ralf

I see. Unfortunately, the switching between bash and csh is needed until the next release. I am not quite sure what this > Another thing is i installed in a user so whenever i do project it gives permission denied . error/problem exactly is or how it can be solved, but maybe some of my collegues have an idea.

This trick should work: bash prompt $ csh csh prompt % source phenix_env csh prompt % bash bash prompt $ Providing a phenix_env.sh is on our todo list. Cheers, Ralf

I guess you can change shell (type csh or so) in a single window for installing, sourcing and running phenix. > In ccp4 there is a file for everything but how to i do for Phenix ! Yes. It is a bit clumsy, I agree. However note that the release you have is still an alpha release (http://en.wikipedia.org/wiki/Development_stage), indicating that not everything is as much in place as one might like it to be. Let us know if you have any (additional) problems.

Dear peter: how to change bash setup ot csh. I understood that the program is written for csh and tcsh how do change to bash format so that it gets installed In ccp4 there is a file for everything but how to i do for Phenix ! Thanking you Ethayathulla
