Re: GRIB2

Hi Alex,

It sounds like you either don't have the latest version of PyNIO
installed (V1.2.0) or else the GRIB2 codetables have been installed in
a non-standard location or are just not there for some reason.

Can you tell me more about your Python and PyNIO installation, like
where you installed the software, and what version of PyNIO do you
have?

If you are running V1.2.0 of PyNGL/PyNIO, then what does the following
report:

import Ngl
print Ngl.pynglpath("ncarg")

Do an "ls" on the path returned from the above command; you should
see a directory called "grib2_codetables". If you don't, then we need
to find out what happened to these files.
