Chris-

Steve is out for a couple of weeks.  I'll try to help you as best
I can.

One guess is that the script when run from crontab does not have permission
to write out the .nts files (last.nts, gemglb.nts) and it is using
a copy that has references to the eta and nmos grids. Check for spurious
.nts files.  You might want put a cd in your script so you cd to a
working directory at the beginning of the script.  Make sure you have
the correct permissions on that directory for the user running the
script.

>Thanks.

Let me know about the NTS files.  If that's not the problem, I'll look
into it further.
