In the new r.mapcalc (4.2) there is a row() and col() function. So, one can
create new maps for each (i.e. a map of every cells row number and another of
every cells column number) and querry them directly, or use them in further
r.mapcalc operations.
GOod Luck.

<> Greetings,
<>
<> Can somebody please tell me if there is a way to identify the file
<> coordinates (i.e. row, col) of a raster map by using the mouse (or any
<> other means) to click on a point in the display. d.what.rast appears to
<> return only the geographic or projection coordinates, but not the file
<> coordinates. Similarly, can a cell be isolated (described or identified)
<> by manually entering the file (or map) coordinates?
<>
<> I am at a loss! All help appreciated.
