To date, nobody's been able to create a new AIN. It's propriety software that Nova didn't provide the tools for.
Your best bet for AI manipulation is to convert your map into a .MIS and use the DFx2 MED... but even then your AI will have to be heavily scripted so that they will do what you want.
I highly suggest going to
www.dfreload.com There's a whole bunch of info on mapping and modding there.
