Thanks for the sample file.  I was able to read it in 2.6, 2.6u2, and 2.7b1
so I'm a bit stumped.

One thing could be that the uncompression of the file didn't work and you
are looking at a bad copy of the uncompressed file.  To read these,
the IDV has to uncompress them into a temporary directory.  These
will be stored in your home directory under the
.unidata/idv/DefaultIdv/tmp/nj22 directory.

I would suggest looking in that directory and deleting the temporary
file.  Look for one that has the pattern of your file name.  Directories
are encoded so it will look something like:


These temporary files get deleted over time, so if you are working
with these data alot, you might want to uncompress the original files
first so the IDV doesn't have to.

Another possibility is that you have a disk quota set on your
home directory and that is causing the uncompression to fail.

Try uncompressing a file that doesn't work now and see if you can
read it in.
