Interactive Horizontal Gene Transfer Detection

Interactive HGT allows you to define your own horizontal gene transfers as well as
discard or reverse horizontal gene transfers found by the algorithm.

Paste your species tree in the Newick format:

Data sets : Matte-Taillez et al. (2002, gene rpl12e, 14 species),
Delwiche and Palmer (1996, gene rbcL, 40 species),
Woese et al. (2000, gene pheRS, 32 species)
