the code you sent looks fine to me. Still I am not sure if I fully
understand what you are trying to say. What do you mean with "each
>From our previous discussion I understand that you work with two sets
of atoms (residues) where each position in one set corresponds to a
position in the other set. This means you know that all atoms are on
structurally equivalent positions and the two sets of atoms are of the
same size. If this is the case, then the SVDSuperimposer is the right
tool and you would include all atoms in the two sets for the RMSD
If you work with 2 proteins where you do NOT know the structurally
equivalent positions at the start, then StructurePairAligner provides
an algorithm to align two proteins (of different length) and find
pairs of atoms (residues) on structurally equivalent positions. In
this case, the RMSD calculation considers the positions that are
equivalent and ignores the unaligned regions. Guess I should create a
wiki page for explaining this difference between SVDSuperimposer and
