Re: [netcdf-java] joinExisting aggregation

Hi Eli:

It should work as you have it. Can you make me a little example that recreates the problem?

I'm trying to aggregate a set on Netcdf files and have run into a
problem. The dimension I am trying to aggregate over is called datum,
but there is no datum variable, just a number of variables with
dimension datum. So I get an error like:

no coordinate variable for agg dimension= datum

My understanding is that I can create a variable datum using NCML in
this way:

<?xml version="1.0" encoding="UTF-8"?>
          <variable name="datum" shape="datum" type="int">
             <values start="0" increment="1" />
         <aggregation dimName="datum" type="joinExisting"
recheckEvery="15 min">
                <scan location="." suffix=".nc" />

But I continue to get the same error, as if no new variable is created.
Perhaps I am unable to use this method with the scan object? Or must the
dimension and variable be called "time".

Any insight would be appreciated.
