[GRASS-user] Raster: r.report vs r.info

Hi Everyone,

I am having trouble with creating categories for a raster map (floating point).

I used r.reclass to create a category for my raster (temperature values; floating point).  I thought I successfully added categories but when I ran r.report there are no categories; however, when I run r.info for the raster it shows that I have two categories.  

Can anyone give me a hand with this problem?  The results of the r.report and r.info are below:

r.report:

GRASS 6.4.0RC6 (MacrophytesGIS):~/grass/MacrophytesGIS/PERMANENT > r.report mynatemp4reclass
