[MITgcm-support] "gluemnc grid.t*.nc" omits many variables

Hi Maarten,

Originally the gluemnc script did not work with the grid files at all.  
I modified it last year in order to allow glueing of grid files, and  
it does work for me without producing the errors you described. The  
problem could depend on your particular versions of nco, perl, shell,  
etc.

Maybe if you could find the very first error produced, I might be able  
to give you some hints about why it is failing. (Many of the  
subsequent errors could be caused by one initial failure.) But since  
glueing netcdf grid files is not a very common practice (I'm the only  
person I know of who does it), you might have to just try debugging  
the script yourself. A good place to start for this is the nco user's  
guide:
http://nco.sourceforge.net/nco.html

Good luck!

-Ryan
