[ccp4bb] question about powder diffraction

reflection at, say, 45 degrees? There will be a grain oriented in the powder such that x-rays reflect at 45 degrees and so forth. I would expect a continuum of reflections... thanks for the insight. Kianoush

combine phases from this procedure with the Selenium SAD phases, as already suggested. Kianoush --- On Thu, 9/1/11, Basudeb Bhattacharyya wrote: From: Basudeb Bhattacharyya Subject: [ccp4bb] Low resolution structure determination advice To: CCP4BB@JISCMAIL.AC.UK Date: Thursday, September 1

Re: [ccp4bb] To improve xtal quality

Hi, I had the same problem with my crystals because they grew as thin plates. My precipitant was PEG8000, and the crystals grew thicker with addition of glycerol or ethylene glycol. Best, Kianoush --- On Mon, 6/16/08, shivesh kumar <[EMAIL PROTECTED]> wrote: From: shivesh kumar &

[ccp4bb] Refmac Error

refinement runs fine (I see refinement cycle statistics etc.), however, no pdb or mtz file is written out. I use CCP4 version 6.0.2. Thanks for your suggestions, Kianoush * Kianoush Sadre-Bazzaz Graduate Student, Chris Hill Lab University of Utah Biochemistry Department 15

[ccp4bb] Low resolution structure refinement

not as judged by the Rfree, or is the 28-31% difference acceptable at this resolution? 3) I have the same sort of problem when including phases in the refinement. Thank you, Kianoush * Kianoush Sadre-Bazzaz Graduate Student, Chris Hill Lab University of Utah Biochemistry

[ccp4bb] Merging datasets

%, but when I add 50 images (or so) of another, supposedly isomorphous crystal, my Rmerge goes up to 20%. I was wondering if anyone has encountered a similar problem or can offer any suggestions. Thanks so much, Kianoush - Choose the right car based on your

[ccp4bb] rotating a map

ot right. I computed NCS operators from one crystal form into another (and vice versa) and both times the maps are shifted. Any help is appreciated. Thanks in advance, Kianoush - Choose the right car based on your needs. Check out Yahoo! Autos new Car Finder tool.
