Dear Moritz: I wish to express my gratitude for your valuable advice. Thank you. It succeeded when having tried as follows:
0 thru 100=1 0-100m 100 thru 200=2 100-200m 200 thru 300=3 200-300m 300 thru 400=4 300-400m .... end save as alt_class.txt r.reclass input=old_rast_map output=new_rast_map < alt_class.txt r.stats new_rast_map -c Thanks !!
