Re: [phenixbb] TLS makes my r-factors shoot through the roof

I like the new version but it does not seem to have helped much. Before it shot up by 3%, this time by 2.5%. [image: Inline images 1] =/ On 29 May 2012 13:39, Morten Groftehauge wrote:

My version is 1.7.3-928. I'll try downloading the nightly and see if it goes away. Don't know why I didn't think of that first.

Thanks

Hi Morten,

I'm sorry about the problem.

Are you using the latest Phenix? There was a bug in phenix.refine that I fixed a while ago, and the bug behavior was very similar to what I see happening in your case.

Could you please try the latest version and see if the problem goes away? Please let me know.

Pavel

Hi Phenixbb,

3.2A data, 110 Wilson B, I41, twinned. Imperfect inverted repeat dsDNA with 4 protein monomers, NCS not used in refinement. If I don't include TLS I get a nice stable R-factor while RMS goes down. If I include TLS (whether as one group per chain or as chosen by Phenix) this happens:

Density disappears around some of the DNA bases as an obvious difference. If I run Refmac with TLS it just never finishes.

While I could just refine without TLS this does make me worried that there is something wrong with my model or my data (besides being terrible).

Cheers, Morten
