Jo Whittaker has sent me the pdf of her slides, along with the shell script she ran to generate the figure and the line and point files. I have uploaded these files as a zip archive (that has been cunningly renamed as a pdf file to allow me to upload to wordpress, just removed the .pdf from the file and upzip it as normal).
If you want to recreate Jo’s figure then install GMT on your machine, unzip the archive and run the .sh file. You will also need the bathymetry, which can be downloaded from https://www.ngdc.noaa.gov/mgg/global/global.html (and is about 900 Mb). If I can get this on to a local drive I will do so in the coming weeks.
Finally, if you want to use Gplates for visualising/convertign things, then you can get it from http://www.gplates.org/.
Here is the zip archiive: Archive.zip
