[ldmMcidas #KHY-214172]: ldm help help pnga2area / MCIDAS ?

Hi Mike,

As you likely know, I am logged onto the FIT LDM machine and am actively
investigating why the ldm-mcidas 'pnga2area' decoder is not being run
from the pattern-action file action:

MCIDAS  ^pnga2area Q. UI (.*) (.*) (.*) (.*) (........) (....)
        PIPE    -close
        pnga2area -vl /home/ldm/data/gempak/logs/dcsat.log
        -a /home/ldm/etc/SATANNOT
        -b /home/ldm/etc/SATBAND
        /home/ldm/data/gempak/images/sat/goes13/\4/IR/IR_\5_\6

To test whether the 'pnga2area' binary (/home/ldm/decoders/pnga2area) works,
I modified the pattern-action file (/home/ldm/etc/pqact.conf) to include
FILEing of the original product in 
/home/ldm/data/gempak/images/sat/goes13/4km/IR
(the directory that the action above is supposed to write into.  As soon as
I saw the receipt of a new GOES-13 IR image (I was running 'notifyme' to watch
for the arrival of new MCIDAS (aka UNIWISC) image products), I ran the following
by hand:

cat data/gempak/images/sat/goes13/4km/raw/IR/IR_20120806_1945 | pnga2area -vl 
/home/ldm/data/gempak/logs/dcsat.log -a /home/ldm/etc/SATANNOT -b 
/home/ldm/etc/SATBAND 
/home/ldm/data/gempak/images/sat/goes13/4km/IR/IR_20120806_1945

This _correctly_ resulted in:

- the creation of the log file /home/ldm/data/gempak/logs/dcsat.log
  with an entry that looks like it should:

Aug 06 20:01:30 pnga2area[27118] NOTE: Starting Up
Aug 06 20:01:30 pnga2area[27118] INFO: output file pathname: 
/home/ldm/data/gempak/images/sat/goes13/4km/IR/IR_20120806_1945
Aug 06 20:01:30 pnga2area[27118] NOTE: unPNG::  1076666   4724488  4.3881
Aug 06 20:01:30 pnga2area[27118] NOTE: Exiting

- the creation of the correctly decoded output file:

  -rw-r--r-- 1 ldm ldm 4724488 Aug  6 15:59 IR_20120806_1945

This experiment unequivocally demonstrates that there is no problem
with the ldm-mcidas 'pnga2area' decoder.

Now the question is why the standard GEMPAK action for decoding the
image using 'pnga2area' is not working!  To figure this out, I am
implementing a new pattern-action file action that will log things
like the PATH in-scope during the execution of the action; etc.
I will get back to you and Steven when I learn more.

Cheers,

Tom
