Hey Pansy
Perhaps you could try PYMOL. If your mol2 file has proper residue names,
PYMOL gives you acceptable pdb file. However, pymol may consider all
residues as HETATM, which you may want to convert to ATOM.
Hope this helps
Cheers

Hello David
"Have you tried using LEaP: use loadmol2 followed by savepdb? You may
have to do some experimentation and hand editing (either of the input or
output file), but it may get you close."
Yes I tried that too
and this is the error i get
Loading PDB file: ./GC-hexamer.pdb
-- residue 1: duplicate [ C] atoms (total 114)
-- residue 1: duplicate [ H] atoms (total 136)
-- residue 1: duplicate [ N] atoms (total 48)
-- residue 1: duplicate [ O] atoms (total 68)
-- residue 1: duplicate [ P] atoms (total 10)
ATOM NAMES IN EACH RESIDUE MUST BE UNIQUE:
(same-name atoms are reduced to a single atom)
Unknown residue: RES number: 0 type: Terminal/last
..relaxing end constraints to try for a dbase match
-no luck

Is there any module on amber which can add atomtypes to the existing pdb
file

Have you tried using LEaP: use loadmol2 followed by savepdb? You may
have to do some experimentation and hand editing (either of the input or
output file), but it may get you close.
