Selection of structure factors for DM
by Graeme Winter 18 Dec '08

18 Dec '08

Hi Folks, If I am using phenix.autosol for my phasing and dm, is there a way I can specify the "native" FP to use for phase extension? What I would like to be able to do is use a named wavelength for this rather than a synthetic data set composed from all input data... I used to do this with resolve by cadding in the chosen columns (F, SIGF) after solve and then telling resolve what columns to use. Would be cute to be able to not do this! Am running from the command line interface. Thanks, Graeme

Thanks for the reply. I think I didn't explain myself properly, of course I want to do bss, but we have noticed that previous versions of phenix (1.24 I think) did bss once per macro cycle and now with the newer versions, we get the same plus a final bbs cycle at the end of the whole process -shown in red- Is that final cycle introduced by default in the newer versions? Thanks again. Cesar.

Thanks Ralf, You were right. I found that my .log file has Anomalous flag:True. As it was pointed out, my mtz file was came from ccp4 where it uses anomalous data by default. Another small wondering is about differently automatic(?) resolution pick up: my refmac assigned resolution range between 1.48 and 54.23 whereas my phenix.refine set it between 1.363 and 31.041 by default. Also while the refmac provides both entire and high resolution bin completeness, the phenix only gives a whole completeness. Is there any way I can investigate high resolution bin completeness? and why I have different resolution ranges by default without specifically assigning them? Thanks again.

Hi Rupert, Thank you very much for the files! I found a simple, universal trick to "do the right thing", not just in phenix.refine. This will be in future releases. Ralf

Completeness issue by phenix
by Young-Jin Cho 15 Dec '08

15 Dec '08

Hi, I was happy for using phenix but am struggling with a strange result on completeness calculation. One typical data set I used kept showing low completeness, so I used the same mtz, and pdb file on Refmac: it turned out has more than 98% whereas phenix.refine gave me about 46% completeness. I have slightly lower value of R but higher Rfree from phenix calculation without adding H atoms. I don't know if this is a bug or a problem on my data set (hopefully not). thanks in advance, YoungJin

Re: [phenixbb] individual anisotropic adps

Currently phenix.refine does not support refinement of individual anisotropic ADP and TLS for the same set of atoms (see my previous email). However, in phenix.refine you can refine TLS and individual anisotropic ADP for non-overlapping set of atoms. Pavel.

individual anisotropic adps
by gerwald jogl 11 Dec '08

11 Dec '08

Hi All, I was wondering if there is information/recommendations out there for the resolution required to refine individual anisotropic adps. I think the recommendation for shelx is at least 1.5 A resolution. In addition, is phenix set up and would it make sense to combine tls with individiual anisotropic adps? All comments welcome, Gerwald

Keeping the same origin
by Mo Wong 11 Dec '08

11 Dec '08

Hi all, I would like to compare maps from different phasing runs, so it would make my life much easier if I could keep the same origin. I recall this could be done in solve/resolve, but can't seem to find it mentioned in the phenix documentation. Any suggestions? Thanks!
