This looks correct.

I see the problem right here.  The copy of ROUTE.SYS distributed with
ldm-mcidas has the various PostProcessing entries turned off (SUSpended
in McIDAS parlance):

The entries you are probably concerned with are CI, CV, CW, and N1 - N8.
These can be turned on from a McIDAS-X session as follows:

<login as 'mcidas'>
cd workdata
<start a McIDAS-X session>
<verify that you have a REDIRECTion that points to the copy of ROUTE.SYS
in /data/mcidas:


<turn on the PostProcessing actions>

ROUTE REL N1 N2 N3 N4 N5 N6 N7 N8

Once the actions are activated (not turned off), the PostProcessing
should proceed IF the Bourne shell script 'batch.k' that is being
run by pnga2area has been properly configured (edited to set needed
McIDAS environment variables).

Also, the names of the McIDAS BATCH files that are kicked off by the
ldm-mcidas version of ROUTE.SYS were changed to more correctly identify
the satellite platform:

   old BATCH file name        new BATCH file name
        IR8.BAT                   GE-IR.BAT
        VIS8.BAT                  GE-VIS.BAT
        H2O8.BAT                  GE-WV.BAT
        IR9.BAT                   GW-IR.BAT
        VIS9.BAT                  GW-VIS.BAT
        H2O9.BAT                  GW-WV.BAT

>SATANNOT and SATBAND are the supplied new items.

OK.  I would have put these in ~ldm/etc, but this has nothing to do
with the PostProcesses running.

>This effort produced none of the old gifs, so I copied back in 
>the old ROUTE.SYS, and now I get gifs with black (empty) graphic

Hmm...  I can't explain this one unless it is an indication that
you are decoding the CIMSS products using the routing table and
your old routing table does not have CIMSS product entries.

Yes, exactly.

OK.  These pqact.conf actions are now archaic and can be removed.

OK, here is another place where the ldm-mcidas routing table entries
don't match your system.  The new routing table is trying to run
GE-IR.BAT and you have a file called IR8.BAT that you want to use.
You can either change the routing table entry to run IR8.BAT or
you can rename your BATCH file to GE-IR.BAT.

Hopefully, you have moved the BATCH files you want to use to the 
~mcidas/workdata directory and not left them in ~mcidas/data.  The
reason for this is that the old BATCH files will be overwritten by
new McIDAS-X installations if they are left in ~mcidas/data.  The
other option is to rename the BATCH files, but that then requires
you to change your routing table entries that kick off PostProcessing.

If you decide to use the ldm-mcidas routing table, you should affect
the name change while moving the BATCH files from ~mcidas/data to

>But how do I get these things to play ball with the new pnga2area 

They should play automatically IF the routing table entries are
setup correctly (i.e., not SUSpended and reference BATCH files
that exist).

Here goes:

o the PNG compressed GOES-East (GOES-8 right now) image is sent to
  your LDM machine.  It will have a header that looks like:

  pnga2area Q1 UI 151 GOES-8_IMG 10.7um 4km 20000921 1715

o your LDM's pqact.conf file will have an entry that is what you
  sent above:

MCIDAS ^pnga2area Q. (..) (.*) (.*) (.*) (.*) (........) (....)
       PIPE    -close
       pnga2area -v
       -a /data/mcidas/SATANNOT -b /data/mcidas/SATBAND
       -l /unidata/ldm/logs/mcidas.log
       -d /data/mcidas -r \1,\2

o pnga2area needs/expects ROUTE.SYS to exist in /data/mcidas AND it must
  be readable and writable by the user running the LDM

o ROUTE.SYS should have an entry for product UI that looks like:

  UI GOES-East US IR Band 4     150-159      none        none    GE-IR.BAT    3

o after the GOES-East IR product is correctly decoded, pnga2area attempts
  to run the command:

  batch.k UI n yyddd hhmmss cc "GE-IR.BAT
          |  |   |     |    |     |_______ BATCH file name
          |  |   |     |    |______________ ingest condition code
          |  |   |     |___________________ TIME (HHMMSS)
          |  |   |_________________________ DAY (YYDDD)
          |  |_____________________________ AREA file number
          |________________________________ Product code

o you should have setup your LDM account to have a ~ldm/decoders directory
  in which you have copied the Bourne shell script 'batch.k' (distributed
  with ldm-mcidas; you must already have an existing copy that is
  configured correctly).  ~ldm/decoders/batch.k must be executable and
  ~ldm/decoders must exist in the PATH of the user running the LDM.
  NOTE: you should NOT have _any_ McIDAS environemnt "stuff" defined
  in the LDM environment: no environment variables; no PATH entry for
  ~mcidas/bin; and no LD_LIBRARY_PATH entry for ~mcidas/lib!

o the Bourne shell script, assumed to be configured with necessary
  McIDAS environment variable information, is the thing that is run
  by pnga2area.  'batch.k' will, after setting up needed McIDAS environment
  variable "stuff", run the "real" McIDAS BATCH command (~mcidas/bin/batch.k).

o the "real" McIDAS BATCH command will run the named BATCH file IF it exists
  and can be found in the MCPATH set in 'batch.k' script, or if there is
  a McIDAS REDIRECTion, contained in ~mcidas/workdata/LWPATH.NAM, that
  locates the BATCH file

>Much thanks, -Neil

I think that after you RELease the entries in the ldm-mcidas version of
ROUTE.SYS and change the names of the McIDAS BATCH files you are using
to match the ROUTE.SYS entries, your PostProcessing will once again be
operational.  Please let me know if this is not the case.
