[GRASS-user] problem with python scripting

GRASS GRASS user
1

Dear users,
I am writing a script and I’m having problems with the flags for mapcalc

gscript.mapcalc(‘endmember_rstr.1 = null()’, flags=“o”)

ERROR: output map <endmember_rstr.1> exists. To overwrite, use the
–overwrite flag
Traceback (most recent call last):
File “”, line 1, in
File “/usr/lib/grass70/etc/python/grass/script/raster.py”, line 103, in mapcalc
quiet=quiet, verbose=verbose, overwrite=overwrite)

File “/usr/lib/grass70/etc/python/grass/exceptions/init.py”, line 68, in init
msg = _(“Module run %s %s ended with error”) % (module, code)

with other modules flags are working as I expect, like…

Am I missing something?

Thanks!

If you are using GRASS 7.+, the overwrite flag should be written in full, i.e.,

Hi Paulo and thanks for the answer… but It gives me a very similar error if I write the full flag… (The only difference is TypeError… str if I use ‘o’ and int if I use ‘overwrite’… )

gscript.mapcalc(‘endmember_rstr.1 = null()’, flags=“overwrite”)

ERROR: output map <endmember_rstr.1> exists. To overwrite, use the
–overwrite flag
Traceback (most recent call last):

Thanks Paulo and Sören for helping!
overwrite=True made the trick! Is this documented somewhere and I just missed it??? Or should I fill a ticket?

Ah, yes, sorry for my wrong answer… too much in R mode (where one would write it as I mentioned).

It is mentioned here: https://grasswiki.osgeo.org/wiki/GRASS_Python_Scripting_Library , but not in a very explicit way I have to say.
