+The extent of all resulting raster maps is taken from the settings of the
+actual computational region (which may differ from the extent of the input
+raster map). The resolution of the computational region however has to be
+aligned to the resolution of the input map to avoid artefacts.

 Reinterpolation (resampling) is done to higher, same or lower resolution 
 specified by the <i>ew_res</i> and <i>ns_res</i> parameters.
