euler_transform ( euler_angles,  translation )

Rotation applied first, then translation.

euler_rotation (
        phi,
        theta,
        psi,
        )

Convert Euler angles to an equivalent Chimera transformation matrix.

Angles must be in degrees, not radians.

Uses the most common Euler angle convention (the chi-convention) described at

transform_atom_coordinates ( atoms,  xform )

Apply a rotation and translation to atoms.
