Re: THREDDS : need help for aggregation

Hi Tony:

Can you figure out if theres a problem with the TDS vs a problem with ferret?

A couple of ways of doing that:
 1) use the browser interface to look at the TDS output to see if its what you 
expect.
 2) use another dods client like the Nj22 ToolsUI.

Since I dont know how ferret works, its hard for me to figure out this problem.
