Robb,

Thanks so much for the help.  However the /pub directory I'm trying
to write to has 970 Gbytes free and the netcdf files I'm trying to
duplicate or possibly replace with 1x1 deg for 1.25x1.25 deg are 5
Mbytes each so there should be plenty of room.

How does one run gribtonc on command line?  I'm being dense here,
but trying to cat individual HHxxxx files into gribtonc gives a
segmentation fault and  I cant think how else the PIPE would work on
command line.

ie I'm trying to go
cat HHMA40 | /usr/local/ldm/decoders/gribtonc -v HHMA40 -q
"lin,dlat=1.25,dlon=1.25"
/usr/local/ldm/decoders/cdls/avn-1.25x1.25.cdl test_nc

Teresa,

Maybe something else is going wrong.  Here's the command line I use that
sends the errors to the screen, then we can see what's wrong.

% /usr/local/ldm/decoders/gribtonc -v -l - -q "lin,dlat=1.25,dlon=1.25" \
/usr/local/ldm/decoders/cdls/avn-1.25x1.25.cdl test.nc < HHMA40


Robb...

trying to use <HHMA40 on the end of the gribtonc doesn't work either
