Hi Jeff,

Hopefully, but probably not.  Segmentation violations are typically due to 
something
else.

No.

Absolutely no!

OK.

You (we) will need to be concerned that the actions that were added to your
~ldm/etc/pact.gempak pattern-action file are properly backed up before removal.
I suggest copying the file to a backup before proceeding.

A quick look at your ~ldm/etc/ldmd.conf file shows that there are McIDAS 
processing
actions being used.  It is likely that those actions are in your current 
~ldm/etc/pqact.conf
file.  We may want to revisit those _after_ your GEMPAK decoding is 
straightened out
(I do McIDAS support here at the UPC).

Which "decoder stuff" did you remove?

Yes.  The procedure is explained in the GEMPAK pages of our website:

Unidata HomePage
http://www.unidata.ucar.edu

  Unidata GEMPAK
  http://www.unidata.ucar.edu/software/gempak

    Site Configuration for Products
    http://www.unidata.ucar.edu/software/gempak/GEMPAK/configuration.html

Basically, if your 'gempak' account has been setup properly, all you need
to do is run the script $NAWIPS/ldm/etc/gen_pqact.csh.  I say setup properly
because the environment variable NAWIPS will have to have been setup to
invoke gen_pqact.csh.

> I'll keep you posted on how things progress here...

Very good.  I think you are very close to getting things setup correctly!

> Thanks again.

No worries.

Cheers,

Tom
