The following error occurs when a typo is made on the specified train directory.

  warn("Input master not specified. Generating.")
Traceback (most recent call last):

There should be a clear and obvious error message if you have accidentally specified an incorrect train directory.

I'm guessing my mouse wheel slipped while the dropdown box still had focus. Sorry!
