[GRASS-user] help with g.pnmcomp

[Alberto Pettazzi]

Hi everybody,

I want to write a script that creates an image of raster A superposed to 
raster B. I want that raster A have an opacity of 0.6.
I tried with the command:

g.pnmcomp input=raster_A,raster_B opacity=0.60,1 output=image_C 
width=800 height=640
but it appear the following error message:

ERROR: File <raster_A> not found

BUT I know there is.

So, what am I doing wrong? Do I have to do something more first ?

thank you in advance
