Thanks. I'll do that by today.
Do you know anyone who should I contact about opening 5.nc files or how to
change the z variables ?
The problem with 5.nc is that is it missing the "positive" attribute
on z. According to the CF docs:
"Other vertical coordinates must use the attribute positive which
determines whether the direction of increasing coordinate value is up or
down"
Also, the units for sea_water_potential_temperature are wrong. C is
Coulombs. I should be celsius.
I've attached an NcML file that you can place in the same directory
as your 5.nc file. That will add in the positive attribute to z
and fix the units.
Also, for your other files, you can try using the CDM validator:
http://motherlode.ucar.edu:8080/thredds/cdmValidate.html
which will show you some information on what might be wrong with the file.
Thanks to Tom and John Caron for their help.

Before you Display the field, try reducing the number of points (in
the Field Selector, the lower right-hand panel, the "Stride" tab) --
try every 5th point or something like that. After that, then create
the display.
Also, of course, you will need to change the "range" of the color
table -- since that -10738..2 value I assume is a bad data value.
Just right-click on the colorbar in the Control, etc.

I had a few minutes over lunch and made you a movie. It uses every
5th point in your grid (although you might be able to get away with
every 4th or even 3rd). You can pick up the file at:
<ftp://ftp.ssec.wisc.edu/pub/ssec/tomw/maswood.mov>
It is about 90MB and will be on the server for only a couple of days
(auto-purge is our policy).
I was not able to open 5.nc. The NetCDF Tools do not find any "grids"
in the file, either. Must have something to do with the 'z'
coordinate variable. You'll have to get someone at Unidata who knows
about these things.

Hello Tom,
I am able to see the pic which I attached with this email.
Is it possible for you to upload the animation/movie through
"http://www.yousendit.com/ "
so that I can understand what the animation look like.
I tried the both version 2.5 and 2.6 nightly build after reducing the
memory
to 1200MB.And I think my graphics card installed properly though I'll
test
with other pc.
And are you able to open 5.nc file ?
Thanks
Maswood
