Re: Method 2: netCDF output with file predefinition

It looks like you are hitting the 2 Gb limit.

I should have mentioned this earlier: before your addfile call, try
adding this call:

   setfileoption(a,"Format","LargeFile")

Be sure to replace with the file pointer returned from your
call to "addfile".

Please see:

for more information.
