A standard orientation is anything you want it to be and is usually defined in the context of orthogonal axes. It is simply a reference point from which you apply the results of your search. We usually use one or more of the orthogonal axes as a starting point for easier visualization.

[ccp4bb] GLRF and interpreting self rotation functions...

2009-04-01 Thread Francis E Reyes
I am experimenting with GLRF and am having trouble calculating the locked self rotation function for a protein of known structure. The protein has a 3 fold NCS axis that is not parallel to a crystallographic axis. I'm at the step of specifying the local symmetry elements for the locked sel
