Use the script '''>TRIP2/map/extract.sh''' which uses the NCO commands to extract flow direction and elevation first; then use '''>TRIP2/map/calc_rivseq.f''' to calculate river sequence based on the extracted flow direction map.
Example: Extract the Indochina region from the 1.0 degree global maps
->'''[thanh@shui map]> more extract.sh'''
-># extract indochina region from the Global map
->ncks -d lon,93.,109.5 -d lat,8.,34. 1.0_deg_elevtn.nc ic_1.0_deg_elevtn.nc
->ncks -d lon,93.,109.5 -d lat,8.,34. 1.0_deg_flwdir.nc ic_1.0_deg_flwdir.nc
