Select positive values only

Added by Almami Johnson about 10 years ago

Dear All

I'm just wondering how to select positive values only from an input file and save them in an output file while putting all negative values to 0.

Thanks.

Try the CDO operator setrtoc:

    setrtoc   Set range to constant
                       / c      if i(t,x) GE rmin AND i(t,x) LE rmax
              o(t,x) = 
                       \ i(t,x) if i(t,x) LT rmin AND i(t,x) GT rmax
Syntax:
    setrtoc,rmin,rmax,c  ifile ofile
Example:
   cdo setrtoc,-1.e99,0,0 ifile ofile
