Hi Tiziana,

re:

Thanks.

RE:
> Thank you very much for looking into this.

I see two things that are of some concern:

ldmd.conf

The pattern you are using in your REQUEST lines to ldm.madis.ncep.noaa.gov
are not what I would use to request everything.  For instance:

request    FSL2 "\.*"    ldm.madis.ncep.noaa.gov

is probably better changed to:

request    FSL2 ".*"    ldm.madis.ncep.noaa.gov

The second thing has nothing to do with receipt or processing of MADIS
or other data from ldm.madis.ncep.noaa.gov, it is the failure to run
the ldm-mcidas 'pnga2area' decoder on the UNIWISC images that you
are receiving.  Here is an example error entry from the ldmd.log
file you sent:

Apr  3 13:44:31 io pqact[24805] ERROR: [filel.c:1404] Couldn't execute decoder 
"/home/ldm/decoders/ldm-mcidas/bin/pnga2area"

I would check to make sure that:

- /home/ldm/decoders/ldm-mcidas/bin/pnga2area exists

- and, if it exists is it executable?

- and, if it exists and is executable, are all of the shared libraries
  that it needs available

  you can check this by running:

  ldd /home/ldm/decoders/ldm-mcidas/bin/pnga2area

  A listing were all shared libraries are found will look something like:

% ldd ~ldm/decoders/pnga2area 
        linux-vdso.so.1 =>  (0x00007ffe08ddd000)
        libX11.so.6 => /usr/lib64/libX11.so.6 (0x0000003da0c00000)
        libm.so.6 => /lib64/libm.so.6 (0x0000003d9e800000)
        libc.so.6 => /lib64/libc.so.6 (0x0000003d9d800000)
        libxcb.so.1 => /usr/lib64/libxcb.so.1 (0x0000003da1000000)
        libdl.so.2 => /lib64/libdl.so.2 (0x0000003d9e000000)
        /lib64/ld-linux-x86-64.so.2 (0x0000003d9d400000)
        libXau.so.6 => /usr/lib64/libXau.so.6 (0x0000003da0800000)

Cheers,

Tom
