Jim,

Yes, this will work fine.

The problem is the specification of 'pcode' and 'anum'. These values
are extracted from the product header as \1 and \2, respectively
Your entry should read:
MCIDAS ^pnga2area Q. (..) (.*) (.*) (.*) (.*) (........) (....)
PIPE -close
/home/ldm/ldm-mcidas/bin/pnga2area -d /datt1/mcidas -r \1,\2
-vxl log_file_name
You will need to replace 'log_file_name' with the name of the file you
want to log messages in. If this is ldmd.conf, then you do not need
to specify '-l' at all:
MCIDAS ^pnga2area Q. (..) (.*) (.*) (.*) (.*) (........) (....)
PIPE -close
/home/ldm/ldm-mcidas/bin/pnga2area -d /datt1/mcidas -r \1,\2
-vx

Yup. As soon as you make the above change to pqact.conf; check the file
integrity with 'ldmadmin pqactcheck' (for recent versions of the LDM);
and send a HUP to pqact, your system should start decoding the images.
I have been advising people to modify their 'request MCIDAS' line from
ldmd.conf to request only PNG compressed imagery. This may benefit
you when we add more images to the broadcast, as you may choose to
not ingest them since you have a NOAAPORT system.
I would recommend you change your request line to:
change:
request MCIDAS|FSL2 ".*" squall.atmos.uiuc.edu
to:
request MCIDAS "pnga2area Q[01]" squall.atmos.uiuc.edu
request FSL2 ".*" squall.atmos.uiuc.edu
Of course, after a change to ldmd.conf, the LDM must be stopped and restarted
for the change to take effect.
