Re: NCL won't work when calling from script

Hi Walter,

It looks like you might have two versions of NCL installed on your system. The actual "ncl" you are running is V5.1.1. The $NCARG_ROOT environment variable, however, seems to be pointing to a location that is associated with NCL V5.2.0 or higher.

Can you type the following and send me the output:

    ncl -V
   which ncl
    env | grep NCARG

Sometimes, in the process of typing the above three commands, you'll see right away that NCARG_ROOT is pointing to the wrong location, or, you need to update your PATH environment variable so that $NCARG_ROOT/bin is on your path before wherever the 5.1.1 version resides.
