r.in.tiff

[Malcolm Williamson]

Hi, Joe
You've probably already done this, but I always start out by checking the 
basics:
1. Is your region set to the new raster map? (g.region rast=mapname; 
d.erase)
2. Do you have a MASK on? :)

If these criteria are ok, _and_ you really have data in your cell 
directory, then you might run r.stats or r.report to assess the range of 
values in the file. Good luck,
