[ncl-talk] Netcdf file error

[Mary Haley]

This is a pretty old version of NCL!  I highly recommend upgrading NCL if
possible.

I just tried the file with NCL V6.1.0, and it also works fine.

You had a typo in your command:

ncl_filedump -v corr output_Jan.txt

Just to be clear, ncl_filedump will *not* work on ASCII files. It will only
work on NetCDF, HDF, GRIB, etc, files.

ncl_filedump -v corr output_Jan.nc

--Mary
