Hi Mich<div>Thanks for the reply. I think it has worked but everytime I try to open, my winGRASS goes "bananas".</div><div>Just to sum what I have done</div><div>1- Import a xyz ASCII file that is a float with a range of [166297.00 - 20855944.0] (not all values are used) and Rows: 4655 ;Columns: 4520 .</div>
<div>2- I did r.mapcalc int() to this file that gets the range of [166297 20855944].</div><div>QUESTION: can I apply int to a FLoat with values as big as this?</div><div>3- I did r.mode base=int_base coverage= 11073_B@PERMANENT (it's a high-resolution image) output=output1</div>
<div><br></div><div>Ok it runs (it takes some time as expected)</div><div>Thern if I try to display it freezes... Even If I just try <a href="http://r.info">r.info</a> output1 it also freezes.</div><div><br></div><div>Any thoughts aboutt this? (Thanks Micha)</div>

Greetings<br>
<br>
This new topic is related with <br>
<br>
I need to calculate mode for a base map that is composed by float values.<br>
r.mode base=base@PERMANENT cover=11073_B@PERMANENT output=saida <br>
And I get:<br>
ERROR: reading r.stats output<br>
ERROR: No rules specified<br>
<br>
This means that I'm not being able to apply this function just because my base map is a Float. Any ideas of how to fix this?<br>
</blockquote></div></div>
How about r.mapcalc base_integer=int(base) ?<br>
<br>
The base map should be integer (category ) values, where the mode is calculated for all cells with the same cat value, so it indeed should be an integer raster.<br>
