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 -- Warren L.
