Hi,

I'm trying to perform spline interpolation over about sixty rainfall stations
to construct a rainfall map using  s.surf.tps. I get a raster map with only
one category. I'm generally using default parameters.

Any ideas on what the problem is? i.e. why I only get one category.

Thanks in advance,

P.S: Whilst s.surf.tps is running, I also get a stack of warnings about
site descriptions not beginning with '#'. I assume my site file is in order
because s.surf.idw works fine. There is also a warning about 'minimum number of
sites'.
