@@ -13,7 +13,6 @@ As with most GRASS raster3D modules, <EM>r3.stats</EM> operates on the cell
 array defined by the current 3D region settings, not the original extent and
 resolution of the input map. See <em><A HREF="g.region.html">g.region</A></em>.
 <P>
-The region setting will not effect the memory consumption of this module.
 The number of subranges in case of value range calculation or the number of 
 equal value groups effect the memory consumption and the calculation time.
 You can expect a huge time consumption to calculate the equal value groups (flag <em>-e</em>)
