Dear all,
I am a beginner to tcl scripting. I am attempting to calculate the angle
between the "y" component of the principal axes of 2 domains. I have
calculated the principal axis with the help of the Orient package:
http://www.ks.uiuc.edu/Research/vmd/script_library/scripts/orient/

I would like to compute the angle between the 2nd ​component (y
component) of the axes now.

How can I use the value stored in $I to obtain this information?

Kindly provide your valuable suggestions in this regard.
