Error in derive_streams #21

Closed mjciupak closed 3 years ago

mjciupak commented 3 years ago

Hello! I am trying to use use the derive streams function and running into this error message:

Error in parseGRASS(cmd, legacyExec = legacyExec) The command r.stream.order --interface-description could not be run (127), and produced the error message: /bin/sh: r.stream.order: command not found

Even after installing and reinstalling the add on in GRASS 7.8.4. Any help is appreciated! note: I tried running the command r.stream.order within GRASS and it says the file type in not ’CELL” Would this have anything to do with it?

Maybe it needs a restart after reinstalling the addons in GRASS.

If that does not help, could you please try to run the following in GRASS standalone and post any error or warning messages:

  1. r.watershed with elevation = "dem", accumulation = "accums"
  2. r.stream.extract" with elevation = "dem", accumulation = "accums", threshold = your_accum_threshold, d8cut = 100000, stream_length = your_min_stream_length, stream_raster = "streams_r", direction = "dirs"
  3. "r.stream.order", flags = "z, m", stream_rast = "streams_r", direction = "dirs", elevation = "dem", accumulation = "accums", stream_vect = "streams_v"

Yes, r.watershed and r.stream.extract completed without any errors. r.stream.order came back with the error: ERROR: Raster map <paint_river_5m@PERMANENT> is not of type 'CELL'

Could you send me some (small) test data please to check if there is something wrong with the dem?
