Boyang,
In order to calculate the RMSD between two structures, the program
must first do a "best-fit" superposition of the two structures, and only
then can RMSD be determined. So the coordinates of one of the structure
must be changed to superimpose on the other structure, as well as it was
possible.
Hope this helps.
