[GPlates-discuss] importing seed points

[Mark Brandon]

I am trying to import a list of seed points for the flow line calculation. I have successfully used of opening a gmt file (lon\tlat\r format, line by line) and that shows up in the list of loaded feature collections. (One can also paste the gmt file into the application with the same result.) But it is not clear to me how to convert this feature into a collection of seed points for the flow line calculation.
Best,
Mark
