Robert and Nick,

Are you both using Mac?

Please reproduce the error with small datasets, and send them over to
me along with your exact region settings, r.surf.nnbathy syntax and the
nnbathy version you used (if you built it yourself, specify if "serial
processing" enabled).

Like I said, r.surf.nnbathy has been working well for me. If you want
me to help you I need details.

Cheers,
Maciek
