Coot (and SSM) should give matrix - euler and polar angles! Paul? Eugene?
But if you do the superposition with lsqkab (superpose molecules - match
residues) then that gives all 3 ways.
Or use ROTMAT which converts everything to everything else.. ( rather
clumsy though..)

Dear all:
I want to calculate the rotation angle between two similar domains. By
using Coot, I can superposr the two domain and get the rotation
matrix. But how to convert this matrix to an angle. Is there any
program can calculate this ?
Thanks.
