Hi Tom,

I just double-checked, and there is a tab there.  Full pqact entry is
below; I see now any tabs I had were replaced with spaces when I copied it
to the email.

NOTHER ^TI(S.).. KNES ([0-9][0-9][0-9][0-9][0-9][0-9]) ...
        PIPE    -metadata
        /home/scripts/ldm-alchemy/goes-restitch.py -q -d /home/data/goes -t
60 -e /home/scripts/sat/goes_mcidas/manager.py -p -l
/home/ldm/var/logs/goes-restitch/\1.log \1 \2

As for this not reaching the ldm-users list, that was my mistake.  I forgot
I wasn't subbed with the email I sent it from, so it got flagged as a
non-member.

What's confusing about this is everything else continues to work fine, and
that entry too was working fine, until that sector change.  That tells me
something with the data changed, but the LDM config should otherwise be
okay.  I'm starting to save tiles directly and will keep digging.

Thanks,

-Mike
