Patrick,

To call a script from pqact when a product arrives, you can use the EXEC action,
and pass the name of the file you want to proceess to the script. 
You can also sed the geerated product to your other servers using the pqinsert
command from ldm to place in the local queue for distribution to downstream 
sites.

To modify your script, you would reove the code that finds the cursat, tie etc,
and instead have the script use the input from command line
as called by pqact via the EXEC line.

When generating X based displays using gf or xw, remember that your display has 
to
be large enough to allow the image to be drawn. If you are using a virtual X 
server
on display :1.0, make sure you are running Xvfb with screen size (eg memory)
large enough for your 5000x5786 image.
