TreeStat is an application that can process a set of trees in a PHYLIP or NEXUS tree file and calculate a number of summary statistics for each. These are saved in a tab-delimited file for analysis in Tracer or statistics packages.

A range of summary statistics are included:

  • Tree-balance statistics: Colless’s, B1, N_bar, cherry count.
  • Tree shape: Tree height, node heights, treeness, Pybus’ gamma.
  • Population genetic: Fu & Li’s D, external/internal ratio.
  • Other: Tree length, root-to-tip lengths.

Download versions of Treestat for Macintosh, Windows or as a Java executable.
