With version 0.98 release, you can get this matrix as a standard 4x4
homogenous transformation matrix:
load targ.pdb
load prot.pdb
align prot, targ
print cmd.get_object_matrix("prot")
The matrix is returned as a tuple of 16 floats, where R is the rotation and
T the translation as follows:
(
R, R, R, T,
R, R, R, T,
R, R, R, T,
0, 0, 0, 1,
)
Cheers,
Warren
