Tom,  attached is a simple .nc trajectory generated from this example code
provided on the MMTK Web site:

You can regenerate this yourself by installing MMTK and running the python
on that page.  Here's where to get MMTK:

Other examples are listed here:

Thanks!  Let me know what else I can do to help.

Yours, John
