I'm not sure if this is it but looking at the path to the "os.py" my installation (although OSGEO4W and 7.0.4) shows "Lib" not "lib" ... It it is having trouble finding the os.py file, then the difference in the spelling of lib with a capital letter may be the issue... Could it be that simple ?!?! Chris

When I try I get the following message: v.centroids --overwrite --quiet input=inputmap output=outputmap cat=1000 Traceback (most recent call last): File "C:\PROGRA~1\QGISES~1\apps\grass\grass-7.0.3/scripts/v.centroids.py", line 69, in <module> main() File "C:\PROGRA~1\QGISES~1\apps\grass\grass-7.0.3/scripts/v.centroids.py", line 63, in main grass.exec_command("v.category", type = 'area',**options) File "C:\PROGRA~1\QGISES~1\apps\grass\grass-7.0.3\etc\python\grass\script\core.py", line 536, in exec_command os.execvpe(prog, args, env) File "C:\PROGRA~1\QGISES~1\apps\Python27\lib\os.py", line 353, in execvpe _execvpe(file, args, env) File "C:\PROGRA~1\QGISES~1\apps\Python27\lib\os.py", line 380, in _execvpe func(fullname, *argrest) OSError: [Errno 2] No such file or directory (Wed May 11 08:00:49 2016) Command finished (0 sec) I have no idea what that means and where to look for the error. Furthermore, the final goal is to run v.centroids as part of an external python script that can be started from outside GRASS. When I try this, I get the following message: Process ended with non-zero return code 1. See errors in the (error) output. What ist the "(error) output" of a python script and where can I find it? best regards, Uwe Fischer -- The information contained in this email message is intended only for the use of the individual(s) to whom it is addressed and may contain information that is privileged and sensitive.
