If I recall correctly, your best option was to guess as to what could be going on at the bottom of the window when you found that your screen resolution was not up to the standards set by HKL Research. Of course, I'm remembering from 2001. Under most circumstances one expects software

I have custom O stereochemistry files that make tweaking DNA very easy--if you know how to use O. These days I think it is more stylish to use coot, however. I've never used it for serious work, but I also think coot has strange and wonderful abilities that renders the discrimination of

[ccp4bb] refinement with REFMAC5

Dear All, I am little curious while refining my structure with refmac5. Each refinement of refmac produces two main files one mtz and one pdb. Will there be any difference with taking the latest mtz vs taking the oldest mtz with the latest pdb. Thank you for your help. Sincerely

Couple of things, Ru Heng. 1. What buffer conditions is your protein in? Is it similar to the buffer you describe as using to dissolve your DNA in? In general, you can even get away with dissolving and annealing the oligos in just Tris etc. 2. Play with buffer conditions, particularly

Ru Heng, It is commonly helpful to combine your protein and DNA under dilute conditions and then concentrate the complex. Combining concentrated DNA and protein together has a very good chance of precipitating in my experience. I completely agree that trying different buffer

Hi ruheng, Since you synthesized the oligos, you probably already know if there is any residual salt or buffer in your oligos. I don't know if that caused the problem. Sometimes people purify and desalt the oligos before the annealing step. Joe ruheng wrote: Dear CCP4bbers, I am now

If you have a spare monitor you can always set up your macbook to use multiple screens. Once connecting your spare, go into system preferences, displays, and there you can manipulate the screens to be side-by-side. Regina --- On Wed, 8/12/09, Putcha, Balananda Dhurjati Kumar bput...@utk.edu

Hi Buz, If you have Phenix, you can use the phenix.print_sequence tool to output the sequence in FASTA format. I believe MOLEMAN ( http://xray.bmc.uu.se/usf/xutil.html) can also perform similar function. My best, Jack On Thu, Aug 13, 2009 at 2:34 PM, Buz Barstow b...@mac.com wrote: Hi All,
