This is indicating that both of the following are true:

- you do not have McIDAS installed on your machine

  If you did, the ldm-mcidas decoder 'pnga2area' would be able to find SATANNOT 
and
  SATBAND.

- whoever installed/setup the ldm-mcidas decoders on your system did not
  copy SATANNOT and SATBAND from the etc directory of the ldm-mcidas
  distribution to the ~ldm/etc directory

The images that will get filed in the EAST-CONUS directory are from
the IDD NIMAGE feed which, in turn, come from the NOAAPort Satellite
Broadcast Network (SBN).  The warnings that you report above (note
they are warnings, not errors) relate to the images in the IDD
UNIWISC (aka MCIDAS) datastream, so the problems viewing EAST-CONUS
images in Garp are not related to the pnga2area warnings.

re:

Three things:

- having the SATANNOT.old and SATBAND.old copies in ~ldm/etc should
  have no effect on the pnga2area decoding

- I am puzzled about the pnga2area warning messages you are getting
  given your comment that SATANNOT and SATBAND are to be found in
  the ~ldm/etc directory.

  It may well be that the pattern-action file action(s) that you
  have that run the pnga2area decoder (uncompressor actually)
  do not tell 'pnga2area' to locate these files in the ~/etc
  directory.  A pattern-action file entry that would do this
  would look like the following (this is an example; the actual
  entry would likely be different on your system):

UNIWISC ^pnga2area Q. (U[^ACXY13]) (.*) (.*)_IMG (0.65)um (.*) (........) (....)
        PIPE    -close
        pnga2area -vl logs/ldm-mcidas.log
        -a etc/SATANNOT
        -b etc/SATBAND
        data/gempak/images/sat/\3/\5/VIS/VIS_\6_\7

  You can see from this example, that the '-a' flag tells 'pnga2area'
  where to find SATANNOT, and the '-b' flag tells 'pnga2area' where
  to find SATBAND.

I am interpreting this to mean that your pqact.conf entries all have the
'-a' and '-b' flags for 'pnga2area' invocations.  Am I correct in this
assumption?  If yes, I am have no idea why your 'pnga2area' invocations
would be emitting warning messages like the ones you included above.

Welcome! :-)

What would be useful at this point is you sending us your ~ldm/etc/ldmd.conf
and ~ldm/etc/pqact.conf files (send the files, please don't cut and past
their contents into your reply).

One last comment: I really do think that the problem you are seeing in
Garp is _not_ related to the 'pnga2area' problems you reported.  I should
be able to fully convince myself of this view after looking at your
ldmd.conf and pqact.conf files.

Cheers,

Tom
