Dear Grass users,<br><br>I am having some problems getting something useful out of r.terraflow.short.<br><br>I have a fairly large rasta (Data type CELL, rows: 12,500 columns: 6,250 total: 78125000). My final objective is to get a watershed basin limits and river network. Since the rasta is large and in integer for I have tried using r.terraflow.short. However the command finished in 0 sec and no outputs are generated. The message is as follows:<br>
<i><br>stats.out: File exists<br>STREAM temporary files in /var/tmp (THESE INTERMEDIATE<br>STREAMS WILL NOT BE DELETED IN CASE OF ABNORMAL TERMINATION<br>OF THE PROGRAM. TO SAVE SPACE PLEASE DELETE THESE FILES<br>MANUALLY!)<br>
file stats.out exists - renaming.</i><br><br>when changing the name of the stats.out file I get the following:<br><br><b><i>r.terraflow.short -s --overwrite --verbose elevation=431112@Imatong filled=1fld direction=1dir swatershed=1snk accumulation=1acc tci=1tci memory=100 stats=3stats.out</i></b><br>
