[GEMPAK #RDE-970276]: Warning Decoding

So the warnings display okay when WARN=last?  Then dcwarn is decoding the files 
fine. When you say "open the files directly" you mean that WARN is defined to a 
specific time that you know to exist?  What is the error that you are seeing?

Okay.

Any error messages in ~ldm/logs/ldmd.log will tell you if a program can not be 
found.  As long as the ~ldm/decoders/ directory is linked to a location with 
the decoders available, you should be find.  It's easier to soft link 
~/decoders to /home/NAWIPS/os/linux64/bin than it is to link each decoder 
individually, but either method should work.

I'd be interested to hear more.  Error messages, example files, pqact entries 
and any more information you can provide.
