I am sorry to post this off-topic pymol question here. Thank everyone here for the replies!
The question I give is a "simple" or boring question of the standard trigonometry. However these questions are necessary to be answered for bio-inorganic application (e.g. single bond or double bond, from possible electron distribution to possible reaction mechanism, or you want to know the possible drug insertion between two Trps) when you have very high resolution protein structures or you have a high resolution of small molecule.
The problem is, it is hard to precisely measure these parameters from the standard trigonometry in a 3D space within a display software because it is relate to the many vectors in a 3D space. The hardest part is to display these vectors and measure either the angle or distance among them. I don't think most people know how to do this kind of job and how to access these parameters easily, visibly.
Later, concluded email will be posed for the methods you guys listed here when I have a little bit free time, especially I am still waiting some important relies from PSICO.
Thanks!
Bing

Bing,
I don’t wish to sound unsympathetic, but these are part of standard trigonometry.
