[GRASS-user] problem with r.series / python

[Johannes Radinger]

Hello,

I try to use r.series in a pyhton script as follows:

#%Module
#% description: test-r.series
#% keywords: r.series test
#%End
#%Option
#% key: input
#% type: string
#% required: yes
#% multiple: yes
#% key_desc: name
#% description: Name of input raster map(s)
#% gisprompt: old,cell,raster
#%End

import sys
import os

import grass.script as grass
import grass.script.setup as gsetup


def main():
    grass.run_command("$r.series", input=options['input'],  output="out_Test", method="median")

        
if __name__ == "__main__":
    options, flags = grass.parser()
    sys.exit(main())



but somehow it isn't working. I get following error while running the script:
(Wed May 11 11:13:00 2011)                                                      
test2.py input=density_final_run1 at Treene,density_final_run2 at Treene              
Traceback (most recent call last):

    sys.exit(main())
  File "/Library/GRASS/6.5/Modules/bin/test2.py", line 36,

b/python2.6/subprocess.py", line 1141, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory


is that a problem of r.series or I is there something wrong with my script/options etc.? I use GRASS 6.5 (source from last week or so) on Mac OSX


hopefully someone can help me soon.

/Johannes
