A comparison between BARCE and RECPARS
Tree height 0.3
The simulated DNA sequence alignment was generated with the
program
SIRENS, using the command
data=SIRENS(17,0.15),
where 17 is a random number generator seed
(to allow reproducibility of the results), and
0.15 is the unit branch length.
To download the data (in sequential PHYLIP format),

The true mosaic structure is shown in the figure below,
where the horizontal axis shows the position in
the DNA sequence alignment, and the vertical axis represents the
three possible tree topologies.
Recombinant regions predicted with RECPARS
The horizontal axis represents sites in the alignment,
while the vertical axis represents the
three possible tree topologies.
The columns show the results for different
values of the recombination cost/substitution cost ratio.

Recombinant regions predicted with BARCE
The figure contains three graphs, which show
the posterior probabilities for the
three possible tree topologies,
plotted
along the DNA sequence alignment (the horizontal axis
represents sites in the alignment).
