Hi Everybody

Here is the coordinates due to which I am facing error

ATOM 48 N LYS A 7 10.836 11.349 76.846 1.00
26.10 N
ATOM 49 CA ALYS A 7 11.241 10.032 76.334 0.50

33.37 C
ATOM 61 NZ ALYS A 7 6.729 6.344 75.950 0.50
25.73 N

error occur due to these coordinates of residue 7
this error message showed when I load the pdb file in the tleap
Loading PDB file: ./4iae.pdb
-- residue 7: duplicate [ CA] atoms (total 2)
-- residue 7: duplicate [ CB] atoms (total 2)
-- residue 7: duplicate [ CD] atoms (total 2)
-- residue 7: duplicate [ CE] atoms (total 2)
-- residue 7: duplicate [ CG] atoms (total 2)
-- residue 7: duplicate [ NZ] atoms (total 2)

   Warning: Atom names in each residue should be unique.
     (Same-name atoms are handled by using the first
      occurrence and by ignoring the rest.
      Frequently duplicate atom names stem from alternate
      conformations in the PDB file.)
How I can make changes in the name of these duplicate residues to remove
this error. the pdb file is downloaded from pdb.

Kind Regards
