Dear Case,
Thanks for your help.
I have checked the pdb file and i din't see any duplicate entry of the
coordinates.
I have given the part of the PDB file which has the coordinates of
interest.(I have separated it by giving space for convenience to locate).
I would greatly appreciate if you could tell is there any problem in the
atom nomenclature for the atom that
has these coordinates.
