Hi Gaurav,

Could you please try adding the following lines to your ~/.bashrc file:
export NCARG_ROOT="$(dirname "$(dirname "$(which conda)")")/envs/ncl_stable"
export PATH="$NCARG_ROOT/bin:$PATH"

After adding these lines, you will either need to run “source ~/.bashrc” or open a new shell instance in order to access the “ncl” command.

Kevin

The fact that you are getting an "undefined" error leads me to believe that you might have multiple versions of NCL installed on your system, and that you might somehow be pointing to the older version.
