SPREAD is a Java program supporting processing and visualizations of BEAST’s phylogeographic models (BEAST software).

Contains visualisations (templates), wrapped in a user friendly interface. Supported visualisations include embedded Processing applets and KML output for viewing in Google Earth or any other virtual globe software capable of reading the format.

A tutorial on using SPREAD is availiable here

  • Left panel stretches if a parsed attribute name is long
  • (Continous Tree) Relate the HPD areas shown as polygons in GoogleEarth with specific nodes of the tree
  • Rewrite Log file reader
  • Mean tree calculation (from .trees file)
  • Combobox for relaxed (from parser) / standard brownian motion (rate of 1)
  • Annotate the terminals in the tree with corresponding taxon names
  • Move all the parsing code to reader classes for trees → avoid code duplication
  • Add command line interface for kml templates
  • Fix large scaling factor issues
  • Spread v2.0
