[ccp4bb] scala : SdB

2008-01-17 Thread Bryan W. Lepore
just want to check my understanding on scala. the manual says : "SdB may be omitted in the input and its use is not recommended. Default values are 1.0, 0.0, 0.02" the example shown is : sdcorrection full 1.4 0.11 part 1.4 0.05 .. i.e. if SdB were set, it would have been between the 1.4 and

Vaheh, I don't recall precipitation at all, but I do remember that we were prepared to change the crystallization recipes (i.e. adjust the recipes from previous 'large volume' crystallization to make more nuclei). For example, our first tests were with lysozyme (sorry, hardly a representative

The Structural Genomics Consortium (SGC) is adopting a biology-centered approach to structural genomics: dedicated biology groups with target-specific expertise work on getting the proteins soluble, and biophysical and functional characterizations feature prominently. Interesting biological questio

Actually, in our hands, we have gotten a mixture of clear drops and precipitate when scaling from teeny drops to larger ones. Teeny drops equilibrate faster, and have more pronounced surface and edge effects than larger ones. We have also found that it is easier to crystallize salt in teeny drops (

Surely the original poster meant "alternate indexing possibilites" (as discussed in http://www.ccp4.ac.uk/dist/html/reindexing.html; for his space group there are indeed 2 ways to index), not "alternate origins". Kay Meyer, Peter schrieb: Doubtlessly I'm confused, but my understanding was tha

2008-01-17 Thread Meyer, Peter
Doubtlessly I'm confused, but my understanding was that alternative origins would only be an issue once a dataset was phased (so that wouldn't cause problem during integrating/scaling). I'd thought that using a consistent unit cell during indexing and scaling was a separate issue. Any chance y

Mark, What was the state of the larger drops when tiny counterparts had crystals? My guess - they all precipitated. I'm trying to understand why some proteins or some conditions require change in protein concentration while others do not when migrating from smaller drops to larger ones. If it

This illustrates nicely that the number of crystals per volume unit ultimately depends on the number of nucleants per volume unit. If the surface of your vessel has the power to nucleate it dramatically changes the effect of going to smaller volumes. I guess everybody is right here, depending on th
