Dear Grass users, I am having some problems getting something useful out of r.terraflow.short.
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: * stats.out: File exists STREAM temporary files in /var/tmp (THESE INTERMEDIATE STREAMS WILL NOT BE DELETED IN CASE OF ABNORMAL TERMINATION OF THE PROGRAM. TO SAVE SPACE PLEASE DELETE THESE FILES MANUALLY!) file stats.out exists - renaming.* when changing the name of the stats.out file I get the following: *r.terraflow.short -s --overwrite --verbose elevation=431...@imatongfilled=1fld direction=1dir swatershed=1snk accumulation=1acc tci=1tci memory=100 stats=3stats.out* cell 431112 header compatible with region header Elevation stored as SHORT (2B) Region size is 12500 x 6250 STREAM temporary files in /var/tmp (THESE INTERMEDIATE STREAMS WILL NOT BE DELETED IN CASE OF ABNORMAL TERMINATION OF THE PROGRAM.

Please contact the application's support team for more information.

I have no idea what those two failed indicatores refere to... Am I missing something here? Any tips or help would be great! Thanks, Falk
