antechamber and its prepin files

Hi
I hope someone can assist me.
I am constructing ligands to use in AMBER. My problem is that when I build
a simple molecule (carbon, hydrogen and oxygen) using some program (e.g.
MOE) that will output a pdb file ANTECHAMBER is not able to convert it into
a correct prepin file. I have tried, successfully a few times, to rename the
carbon atoms from C to CA etc. Most of the time it takes hours (to days) for
me to locate something that will make a correct prepin file to load into
xleap. I keep getting carbon atoms and hydrogens referred to as DU in my
prepin files (along with nan0x7ffffffff). Is there some logical format that
I can use to convert my pdb files to a prepin file without this trouble? I
would appreciate any help in this area.


Thanks, Steve
