Sir
I would like to run minimization for a drug molecule
using AMBER package. When i run leap, it shows the
below detials.

Splitting pdb file residue 1 into XXX and G
1 residues had naming problems.
Residues split, so res numbers will not correspond to
pdb.
-- residue 1: duplicate NA1 atoms (total 9)
ATOM NAMES IN EACH RESIDUE MUST BE UNIQUE:
(same-name atoms are reduced to a single atom)

>From the error message, what i could guess is AMBER
forcefield is not assigned for this molecule.
sir, can you please tell me how to modify the PDB file
of this molecular.
If i have the charges calculated using GAUSIAN
package, how will i incorporate those charges in the
AMBER library files.
looking forward to your reply.
regards
deepak
