Re: [ferret_users] when a /append causes a "** netCDF error: Variable not found"



Dear Ferret User Group:

I am unable to figure out what the following error message means. Your help is greatly appreciated.
I have a ferret script (ferret_basic_1.csh) and an ascii datafile(Ferret-Data.txt ). The VAR= string below contains the column names of the datafile and I am choosing which column I want to plot as an argument in the ferret csh script.

Note: I use the attached .csh shell script to run ferret in batch mode with arguments. Only the relevant portion of the .jnl file is attached. I am trying to plot the Column 4 of the ASCII data file by passing its name as argument 3 ($3) of the ferret csh script.

----------------------------------Screen Output with Error Message-------------------------------------------
Unix Prompt $ csh ferret_basic_1.csh

STATIONNAME1 = "GISS"
