I useVersorRigid3DTransform, and the result of registration is composed of 
Versor(1X3),
Final Translation(1X3),
Matrix(3X3),
offset(1X3)
 
Could some body tell me what these different definitions are?
why the final translation and the offset are not the same?
 
And what is the coordinate used in ITK? what directions do x,y,z axes point to?
 
Thanks!


Best Regards!
