Hi Pauline:

As a start can you give the results of giving the following command  
on one of your files:

ncdump -h filename.nc

Also can you give a little more detail about the error you are  
getting - what is it and where are you getting it.  Otherwise it is  
pretty difficult to try and answer.

Regards,


-Roy M
