s.surf.tps

I am trying to generate a DEM using s.surf.tps however the resulting raster
always has a category value of "0" and a label of "no data". However when I
run the same sites list through s.surf.idw it appears to generate a sensible
surface. The format of my sites list is :-

name|sitetest
desc|test for sites list from contpts
377395|7092510|480
377461|7092519|480
377506|7092531|480
377581|7092606|460
etc

When I run s.surf.tps the following error messages for each site are
displayed before it continues processing:-

eg " 400 (line 484) site description not prefixed with '#'"

Does anyone know where I might be going wrong !

Thanks,
Ross Searle

Well, exactly what the message says: your file has to be like:

377395|7092510|#480
377461|7092519|#480
etc.

The # means that 480 is a number and not a category label.

Good luck!
