Dear users,
  I'm trying to install thredds to serve some LDM information
from our ldm site (depresion.dgf.uchile.cl / version:6.4.6).
I am not a Thredds expert, but seems to need "gini" format
to serve satellite images. My ldmd.conf file said:
...
exec    "pqact -f MCIDAS|NIMAGE etc/pqact.gempak_images"
...

my pqact.gempak_images file said (for example):

MCIDAS  ^pnga2area Q. (UY) (.*) (.*)_IMG (.*) (.*) (........) (....)
        PIPE    -close
        pnga2area -vl /home/ldm/logs/ldm-mcidas.log
        -a etc/SATANNOT
        -b etc/SATBAND
        data/gempak/images/sat/MOLLWEIDE/24km/WV/WV_\6_\7


=====================================


I have tried to convert to "gini" with
ldm-mcidas-2004/bin/area2png

#area2png -a /home/ldm/etc/SATANNOT -b /home/ldm/etc/SATBAND -lx - -f

Does exist a better way to have a format ("gini" ??) that can be serve
by thredds ??  may be an option in pqact.gempak_images ??



Thanks in advance
