Hmm...

re:

No.

Since I still had the login information for your machine, I took the
liberty of logging in and poking around.  What I found was a hard-to-see
typo in the actions you added for the GOES-West images in the 
Unidata-Wisconsin datastream (IDD feedtype UNIWISC aka MCIDAS).  The
typo was specifying '-v1' as a flag to 'pnga2area' when the flag should
have been '-vl'.

In case you find this as hard to discern as I did, the typo was

-vONE

instead of:

-vELL

I made the change for you in ~ldm/etc/pqact.conf and then sent a HUP
signal to the LDM 'pqact' instance using:

ldmadmin pqactcheck
ldmadmin pqactHUP

The timing of the change to pqact.conf was opportune for me because
right after making the change some GOES-West (GOES-15) imagery came
in the UNIWISC datastream, and the images were correctly processed
by 'pnga2area'.

Cheers,

Tom
