I have treated with Amber9/Antechamber a molecule (natural product, 98 atoms)
made of two residues (because I had used another suite of programs to calculate
RESP charges, which required to make smaller residues, and pdb atom names were
correct).
I expected failure of antechamber. Actually, it prepared valid parameter and
coordinate files, that allowed correct minimizations."list" on the prepin file
showed as new unit the first of the two residues, in three capital letters. At
all stages, generation of pdb files gave the correct molecule on VMD.
Perhaps what I did is not the equivalent of what is here warned about, althoug
my molecule is seen as two residues on the original suite where the arragement
was done.
