However, the lack of residue specific information allows us to make predictions of disordered segments within proteins shown to contain such segments by CD. hashable Python object can be a symbol, as long as it is present in the alphabet of a sequence. In Greek mythology Procrustes , ("the stretcher") is a son of Poseidon who invited travelers to his home and then stretched (or amputated limbs in later versions) to fit his guests to an iron bed using his smith's hammer. Using the code in the previous section you can verify that rotation matrices corresponding to Euler angles ( or in degrees) and ( or in degrees) are actually the same even though the Euler angles look very different.
