RE: 20050808: LDM write errors from decoders

Steve,
  In the Gemenviron file, I had no leading "/" in front of the setenv
GEMDATA  var/data/ldm/gempak,

NOR did I have a leading "/" in front of the:  setenv LDMDATA
var/data/ldm

I just changed them.  I hope that's it and will let you know.

Nancy

Nancy,

I can help you with GEMPAK decoders and program access to the data.

For the NWX access problems, check your GEMDATA environmantal variable
as configured in your $NAWIPS/Gemenviron file. That should point to your
/var/data/ldm/gempak directory. In looking at the error message you show
below, you are missing the leading "/" in the directory name, and I need
to know if that was a typo, or the root of the problem.

The environmental variable $TEXT_DATA will be set to $GEMDATA/nwx in
Gemenviron, so this also relieas on the GEMDATA variable being correct.
