Greetings I'm having some unexpected difficulties on setting negative valeus to null using r.mapcalc.
I have a raster named d_data (DCELL) with the following range of values | Range of data: min = -0.001399 max = 0.356480 Only a few values are negative so I want to set them to null I have used this expression if(d_c...@national <0 , null(), d_c...@national) and when i do r.info output I get: | Data Type: DCELL | Range of data: min = nan max = nan Which is not expected What am I doing wrong in this expression? Thanks Luisa
