Tutorial 2: Continuous phylogeography of rabies

mlandis edited this page Aug 15, 2012 · 4 revisions

In this tutorial, we'll apply what we learned in Tutorial 1 to a continuous phylogeography dataset (source needed).

####Part A: Getting started

  • Open the rabies dataset as explained in the Quick Start section.
  • Play the animation.
  • Notice how the markers diffuse continuously over space. This is definitive of continuous phylogeography.
  • If your animation is playing, click the Pause button. Reposition the slider to around the year 1995. The timer above the phylogeny corresponds to the slider position.

####Part B: Highlighting controls

  • Highlight interesting lineages by hovering your mouse over branches and markers.
  • Position the mouse over a marker on the map or over a branch on the phylogeny.

####Part C: Masking controls

  • Mask lineages so only markers of interests are allocated area for display on the map. This is useful when you would like have very low lineage-per-area density.
  • Double-click a branch to mask the lineage's continuum (i.e. the root).
  • Single-click all branches of interest to unmask those lineage's continua. (This image shows a paraphyletic group.) Phylowood
  • Finally, single-click the root branch to unmask all the lineages.
