Hi, it seems to me that r.watershed is broken in the latest grass7 trunk version? This may be related to r41705?
Example from the r.watershed manual with spearfish data produces an error: grass_dev/grass_trunk> g.list rast ---------------------------------------------- raster files available in mapset <PERMANENT>: aspect erosion1 quads soils strm.dist bugsites fields railroads soils.Kfactor texture density geology roads soils.Tfactor tractids elevation.10m landcover.30m rstrct.areas soils.ph transport.misc elevation.dem landcover.orig rushmore soils.range trn.sites elevation.dted landuse slope spot.image uparea erode.index owner soil.br.depth streams vegcover grass_dev/grass_trunk> g.region rast=elevation.dem grass_dev/grass_trunk> r.watershed elev=elevation.dem accum=rwater.accum ERROR: USAGE for basin delineation: /1/gebbert/src/grass_dev/grass_trunk/dist.i686-pc-linux-gnu/etc/r.watershed.ram -4 elevation=elevation_map threshold=swale_threshold [flow=overland_flow_map] [drainage=drain_direction_map] [depression=depression_map] [accumulation=accumulation_map] [basin=watershed_basin_map] [stream=stream_segment_map] USAGE for slope length determination: /1/gebbert/src/grass_dev/grass_trunk/dist.i686-pc-linux-gnu/etc/r.watershed.ram [-4] elevation=elevation_map threshold=swale_threshold [drainage=drain_direction_map] [depression=depression_map] [accumulation=accumulation_map] [max_slope_length=max_slope_length] [blocking=overland_blocking_map] [slope_steepness=slope_steepness_map] length_slope=length_slope_map [disturbed_land=rill_erosion_map] [slope_deposition=slope_deposition value or map]USAGE for ARMSED FILE creation: /1/gebbert/src/grass_dev/grass_trunk/dist.i686-pc-linux-gnu/etc/r.watershed.ram [-4] elevation=elevation_map threshold=swale_threshold [flow=overland_flow_map] [drainage=drain_direction_map] [depression=depression_map] [accumulation=accumulation_map] [basin=watershed_basin_map] [stream=stream_segment_map] [half_basin=half_basin_map] ar=ARMSED_file_name WARNING: Subprocess failed with exit code 1 WARNING: category information for [rwater.accum] in [user1] missing or invalid Any suggestions how to fix that?
