r.weight

[DUNN JEREMY SIMON]

Good Morning,

I'm trying to overlay a county boundary file to NDVI map using r.weight. 

r.weight seems to be having problems withthe syntax I am using. r.weight help 
doesn't seem to help. Is ther another way to overlay county line to maps/images


Thanks 

Jeremy 


P.S> r.weight tells me 




weight: assign p09ndvi.imgtest 0 map
What?  Type help for help (syntax error)
weight: weight: 

assign <name> <cat> <val>         assign <val> to <cat> for map <name>

I believe my syntax is correct ?
