[GRASSLIST:3196] Maybe I'm near to solveing the problem with GMT.

[Antonio]

Hi.

I'm trying to get a grass raster file into a GMT compatible form (grd) using the 'grdraster' program. I've set the relative entry into the grdraster.info file but when I execute 'grdraster 10' I get the following:

[Fri Feb 22, 07:11pm][antonio at gaia:~]grdraster 10
grdraster: WARNING - Your grd file is entirely full of NaNs.

OK. "NaNs are cells with no data" but how do I solve the problem of filling those cells with something grdraster will reconize. I know I have to do this in grass but I'm still a newbie with grass and so don't know how to solve the problem.
What I've figured out is that once I've assigned some value to empty cells (NaNs), lets say "null", I must go and fill this out in the grdraster.info file. Right?

Thanks.
