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!
Honestly,
Petr

Subject: [ccp4bb] Calculation of angle between two helix of different subunits
Hello all
I am interested to know about any programme which can calculate the angle between the helices of different subunit not the consecutive helices. 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
