<div>The above is the result I got from the commond r.stats -a <a href="mailto:input=swione@PERMANENT">input=swione@PERMANENT</a> fs=space nv=* nsteps=255</div>
<div>the swione is composited from the r g b maps by importing the tiff swi.tiff. So the category I think is six.</div>
<div>And when I run the comond: r.category <a href="mailto:map=swione@PERMANENT">map=swione@PERMANENT</a> fs=tab I got </div>
<div>9321 <br>26425 <br>31744 <br>32736 <br>32767 <br>Where si the category "0"?</div>

<div>"0</div>
<div>9321 <br>26425 <br>31744 <br>32736 ";, but today it change to six!!</div>
