Self-rotation Patterson maps

Hello,

 I wish to learn about self-rotation Patterson maps such as how to
interpret a map and find out non-crystallographic symmetry. Could you
suggest some good papers (for dummies), web-sites etc.

Thanks a lot for your help.

John

Hi John,

There's some by now fairly ancient tutorial material on the SRF (though of course the theory hasn't changed) here:

http://www.ccp4.ac.uk/dist/ccp4i/help/modules/appendices/mr-bathtutorial/mrbath2.html#section2.8

(and the following section 2.9) and here:

http://www.ccp4.ac.uk/dist/ccp4i/help/modules/appendices/mr-bathtutorial/mrbath5.html

(see section 5.2).

Cheers

-- Ian

Hello John,

In my struggle with self-rotation function, I found this extremely useful to start with. Specially the fig 4 on page 107.


"Characterizing a Crystal From an Initial Native Dataset" by Michael R. Sawaya
http://www.springerlink.com/content/k024q83484477j42/

The peaks in the log files are more helpful than the peaks in Patterson map itself.


all the best
