Re: [ccp4bb] A strange case of MR

You mention that your Rsym is 0.6 - this seems outrageously high (except if the 0.6 is just for your outer resolution bin). If 0.6 is indeed the overall Rsym you have a basic problem of unit cell and space group assignment to reconsider. Check if your processing accounts for all spots and check

> Rsym is 0.6 I'd be seriously worried about this. An R-sym value of 0.6 in the entire resolution range (I assume) means that your reflection intensities do not match. This is the value of the Rsym I could expect in the high resolution bin - in the age of maximum likelihood refinement, not in

Dear ccp4 experts, I'm a beginner and have a problem with the following structure solution. I need great help from you experts. Thanks in advance! The dataset is 1.6A resolution and the spots looks ok, except some smear in the higher resolution. Space group is P1(could be P2 or P21). Completne

[ccp4bb] Important proposed changes in CIF

Dear CIF users, As some of you may be aware, a new CIF dictionary framework is under development. This framework consists of an updated CIF syntax (CIF2), a new set of dictionary attributes (DDLm), and a machine-readable language for describing algorithmic relationships between datanames (dREL).
