The program thinks you have two atoms in your pdb file that have the
same coordinates (51.060 -11.635 48.664). You should check to see if this
is so, of if there is any problem in atom nomenclature for the atom that
has these coordinates, or for any nearby atoms. Also, visually check
the reasonableness of the input coordinates near (51,-11,48).
....good luck...dac
