Dear coummunity
I am wondering if my code for selecting specific raster points (e.g. squares, Quadrate) has a bug. I do not want to plot all squares, because I still have not yet data for all squares. v.extract quadrat out=quadrat_3 where="ID_Quadrat=527190 and ID_Quadrat=569228 and ID_Quadrat=581166" --o The resason is that I get an error on the next line v.to.rast quadrat_3 out=quadrat_3 use=attr attribute_column=ID_Quadrat --o ERROR: Database connection not defined for layer <1> Full Code: r.import input=allema_LZall_UAA_pres_merged.tif output=al_pres --o g.region -ap rast=al_pres v.import input=untersuchungsquadrate_2020_2024.gpkg output=quadrat --o v.info -g quadrat v.extract quadrat out=quadrat_3 where="ID_Quadrat=527190 and ID_Quadrat=569228 and ID_Quadrat=581166" --o v.to.rast quadrat_3 out=quadrat_3 use=attr attribute_column=ID_Quadrat --o r.boxplot -o input=al_pres zones=quadrat_3 output="al_pres_boxplot_3.png" raster_statistics=median -o Thanks a lot Sibylle
