Mike,

>My first problem was that I left out the first 'a' in pnga2area...(see
>below)...oops!  :)

Oops, I didn't see that in your previous email either.

>Now I'm getting some of the areas decoded, but not all of them it
>seems. My lastest entry in pqact.conf is:

>MCIDAS  ^pnga2area Q. (..) (....) (.*) (.*) (.*) (........) (....)
>        PIPE    -close
>        pnga2area

OK.  This looks good if you copied SATANNOT and SATBAND to /usr/local/ldm/etc.

>although, since I have mcidas in /export/home/mcidas/data, and I see
>SATANNOT and SATBAND there I could look for them there with the -a and
>-b.

Yes, exactly.  If your McIDAS installation was such that the HOME directory
for 'mcidas' was /home/mcidas, you wouldn't need to specify the '-a' and
'-b' flags at all.  This was a semi-arbitrary decision on my part based
on my recommendations for installing McIDAS-X under /home/mcidas.

Yes, it should work correctly.  One thing that I have found, however,
is that IF you are decoding the CIMSS images (Q0 time indicator),
and you are using routing concepts to name the files, you MUST add
routing table entries for those products.  Here is what to do to
test your situation:

<login as 'mcidas'>
make sure that you have a REDIRECTion that points to the copy of ROUTE.SYS
and SYSKEY.TAB that is located in the directory into which you are going
to decode images

cd workdata
route.k LIST

Is the routing table OK or is it munged?  If it is OK, and if you don't
have routing entries for the CIMSS products then you should add the
entries:

ftp ftp.unidata.ucar.edu
  <user> anonymous
  <pass> your email address
  cd pub/mcidas
  get CIMSS.BAT
  quit

batch.k CIMSS.BAT

If your routing table is munged, you can do one of two different things:

o regenerate it from DROUTE.BAT
o use the copy contained in the ldm-mcidas distribution

If you use the one in the ldm-mcidas distribution, it should already have
CIMSS product entries.  If you regenerate a new one, then you should:

cd workdata
batch.k LROUTE.BAT            <- the copy of DROUTE.BAT you should have made
                                 at McIDAS-X installation
batch.k CIMSS.BAT

This shows that you are getting the CIMSS images and that they are
either correctly named from a routing table entry, or they are named
using default AREA file numbers.  Are your regular images numbered
in the 5000s?

>I'm not sure where to go from here.

Given the pqact.conf action you included above, and given that you
are receiving PNG compressed images, I suspect the routing table.
Please do a route.k LIST from ~mcidas/workdata to see if the table
is munged.  If it is, follow the instructions above.
