Every other week this question comes up! This is Geometry 101 or beginner's geometry!!! http://www.euclideanspace.com/maths/algebra/vectors/angleBetween/index.htm
I am not sure if it possible to understand _anything_ in crystallography if it is not clear how to calculate an angle between two vectors!

I know about helixang which is a ccp4 supported programme but, i am not sure that does it calculate the relative angle between the two helix of different subunit in different orientation. Suggestiona would be appreciated. Thnaks in advance Peter
