Re: NetCDF error: NetCDF: One or more variable sizes violate format constraints

Patrick,

Check site:
http://www.ncl.ucar.edu/Document/Functions/Built-in/setfileoption.shtml

You should use:
Example 4
In order to write large variables (>2GB) to a NetCDF file you have to set the NetCDF Format option to LargeFile or to NetCDF4Classic.

   setfileoption("nc","Format","LargeFile")
or
   setfileoption("nc","Format","NetCDF4Classic")
