Fishing in the dark: Trying to identify rogue taxa


Alexandros Stamatakis
HITS gGmbH, Germany

The identification of rogue taxa, that is, taxa that randomly scatter across a phylogenetic tree,for instance, because of lack of signal, ambiguous signal, or chimeric sequence data is acurrent challenge in phylogenetics.I will outline some recent algorithmic approaches and experimental resultsto identify rogue taxa for two distinct classes of rogue identification:1. A posteriori rogue identification, that is, identification of rogues by means of a set of bootstrap replicate trees.2. A priori rogue identification, that is, identification (and removal) of rogues prior to conducting a resource-intensive bootstrap analysis.WWW:
