Hi Ufuk:

 /**
  * Open an existing Netcdf file for writing data. Fill mode is true.
  * Cannot add new objects, you can only read/write data to existing Variables.
  */
 static public NetcdfFileWriteable openExisting(String location) throws 
IOException;

We are looking at the possibility to change this, but for now you cant add or 
modify the metadata. You have to rewrite the entire file. ucar.nc2.FileWriter 
is one way to do that.

Hi,

I try to and new variable to an existing netcdf file. I open the file using,

ncfile = NetcdfFileWritable.openExisting(....)

method, but when i adding variable with "ncfile.addVariable(....)", it gives me "not in define mode" error. How can i solve the problem. Is there any other method? Any suggestions will be helpful.

Best wishes,

--ufuk
