Dear all,
i made a python script for grass and it does not work in grass (version in
message subject).
The interface opens but a Windows error states that it is impossible to
open the file, the
file is hence not recognized as a valid command.
the script used to work with osgeo4w 6.4.3 32 bit, if copied in
“…/etc/gui/scripts” directory.
so far I know nothing about your script.
the script is a grass python script i made to automate some processing
and fondamentally uses r.mapcalc to perform map algebra e.g:
grass.mapcalc(“$mapoutfile = abs($inraster)”,mapoutfile=outraster+‘oname’+kf.name,inraster=outraster+‘_’+ofile.name)
why is your script in “…/etc/gui/scripts”? as it states this folder is for
GUI scripts; AFAIR this folder may be not in %PATH%.
This beacause the script have an interface generated by grass parser,
and that is the only way I found to have it run in MS Windows (that worked in grass 6.4.3)
also the scrip flawlessly works in linux.
have you any bat-wrapper for your python script in your %PATH%.
for your python script r.your.script.py living in
C:\OSGeo4W\apps\grass\grass-6.4.x\scripts the bat-wrapper-script
r.your.script.bat should be in C:\OSGeo4W\apps\grass\grass-6.4.x\bin
with following content
{
@“%GRASS_PYTHON%” “%GISBASE%/scripts/r.your.script.py” %*
}
I tried your advice, copied the script in
C:\OSGeo4W\apps\grass\grass-6.4.4\scripts
and made the bat file in
C:\OSGeo4W\apps\grass\grass-6.4.x\bin
but tring tu run it i get this error:
grass output:
