[ncl-talk] Error: Input must have at least three input vertices

[Barry Lynn]

Guilo:

The last message I found about this on the web was from 2012.  So, this
isn't a typical error, and I believe that you need to define your data
better for those who can help.

You could start by providing a PrintVarSummary of data in your file.
