Man, don't you just hate those hackers!!

OK.

Yes, it does sound exactly like the last problem.

I just logged in and see that the only MD files are the ones being
created by the ldm-mcidas decoders for NLDN lightning and FSL wind
profiler data.

Since the problem I fixed last time was caused by the lack of the file
SCHEMA in the directory where XCD decoders create their output, it
strikes me that it would be useful to reorganize how you are storing
your data.  Right now you are putting the XCD decoded files into
/var/data/ldm/mcidas/xcd and the ldm-mcidas decoded files into
/var/data/ldm/mcidas/xdata.  Would it cause you problems if all of the
McIDAS data was put into the same directory?  If you have scripts that
expect the ldm-mcidas produced AREA and MD files to be located in the
/var/data/ldm/mcidas/xdata directory, we could make this a link to the
single directory.  Also, it seems to me that now is the time to get the
latest McIDAS-X release, v2002, installed and running.

What I propose is that I:

1) download McIDAS-X v2002
2) build and test v2002
3) uninstall v7.8
4) install v2002
5) consolidate McIDAS data files into a single directory: ~ldm/data/mcidas
   which is /var/data/ldm/mcidas on your system.  Again, if you have scripts
   that depend on the existence of separate /var/data/ldm/mcidas/xcd
   and /var/data/ldm/mcidas/xdata directories, then we can create links
   to them.

It is possible (likely?) that you have some sort of a setup where the
directories being filled with McIDAS data files are being shared by other
systems.  Is this true?  If so, what would be the impact of consolidating
the McIDAS data directories?

One other question.  I see the directory /var/data/ldm/mcidas/labstuff.
I has a number of Unidata-supplied and Lyndon-generated files like
enhancements, etc.  It also has an LWPATH.NAM file.  Is this directory shared
by multiple systems?

I need to really understand your installation (and get your permission)
before I start making changes.

Tom
