Antechamber is designed for small molecules, not for extended structures
like nanotubes. You will probably need to divide your structure into
smaller pieces, and assemble the bigger ones from smaller ones. See if you
can find a paper that describes the force-field generation process for
tubes that are similar to the ones you have.
