Just an (obvious?) comment: antechamber is designed to estimate force fields
for stable conformers of organic molecules. It's not going to work (for
reasons beyond the specific messages you encountered) for transition states.
You are probably going to need to create a force field by hand. You might
also consider using EVB to generate what you need.
