I checked our version of NBO program and found that it does not
support NEDA in NAO basis. I have contacted Prof. Weinhold and got
the latest source code of NBO 5.x series, namely NBO 5.9. I'm going to
incorporate it into current Firefly source code in just a several
days. I'll post a message to this thread when done.

Kind regards,
Alex
