Dave,

Bummer ;-)

OK, this should be an easy one.

I think that this is telling us what we want to know.  Notice that the time
stamp on VIRT9300 is old (May 25).  This file should be rewritten by the
MCGUI and/or Fkey interfaces, so its time stamp should be current.

You should check to make sure that teh copy of VIRT9300 that the system
is going to use (the one in '.', the current working directory) is
writable by the user trying to run the MCGUI.  If it is not, change it
so it is.  Then when you should see its timestamp change when you run
the MCGUI and put up an image or image loop.  By the way, I have seen
instances where the read/write permission on a file _looked_ like they
would allow writes by a user (the owner appeared to be the very same
user), but the file was not, in fact, writable.  This occurred when the
group of the user got changed after the file was created.  At that
point, the file belongs to a different user even though the user name
was the same (kinda complicated, but I think you get my drift).

>/software/mcidas is the home directory of the mcidas user account, and is NOT 
>writeable by anyone other than the mcidas user.  

OK.  The question is which user was running the MCGUI and getting the map
failure?

>My .cshrc file assigns the environment variables via the if block:

>setenv MCGUI /software/mcidas/bin
>setenv MCTABLE_READ "${MCDATA}/MCTABLE.TXT;/software/mcidas/data/ADDSITE.TXT"
>setenv MCTABLE_WRITE "${MCDATA}/MCTABLE.TXT"
>endif

So the user is _not_ 'mcidas', at least these definitions say as much. Given
that, these look correct.

>Is this a problem with my path?

No, I am 99.9999% sure that it is a permission problem on VIRT9300.

>Help!

Should be an easy one, but let me know if this is not the problem.
