Hi,
have look to the orient package for vmd:
http://www.ks.uiuc.edu/Research/vmd/script_library/scripts/orient/
In the vmd script repository there is also a python script:
http://www.ks.uiuc.edu/Research/vmd/script_library/scripts/fit_angle/
I have done a script using orient which calculate the angle between the principal axes of two
selections. It is very "rough" but is does what you are asking. if you need it contact me
and

There must be several tools to calculate the angle between two domains

wondering if someone has suggestions on any tools, or whether it is possible to
do this using a vmd
plugin directly for a trajectory? IN my case, I have a reasonable good idea
where the hinge is. I
was wondering if the angle between the principal axes of the domains would be
good enough? For
example, if the domains were two discs attached to a common hinge, how can I
find the vector from
the hinge in the direction of each disc?�
