[Qgis-user] GRASS r.mapcalc error

[Michał Bełcik]

Hi everyone

When using r.mapcalc function, it shows an error every time I try to use
it, and the message is "variable LOCATION_NAME not defined", although I
have previously defined the name of the output raster. After copying the
command into the GRASS shell, and adding the name of the file at the
beginning, everything works fine. Can anyone help me with that?

Best

Michal
