you have this matrix? The columns of the rotation matrix are vectors.
There's a very easy way to convert the matrix to a quaternion in Jmol
11.7. You just indicate the first two columns of the rotation matrix,
since those represent the X and Y axes of the "frame" that defines the
rotation.
var c = {x y z} // the center
var q = quaternion({1 0 0} {0 -1 0})
for example. Once you have that you just do
center @c
rotate @q
or, if you don't want to define c and q:
center {x y z}
rotate @{quaternion({1 0 0} {0 -1 0})}
This is Jmol 11.7, not 11.6.
