M. Robinson-rechavi et D. Huchon, RRTree: Relative-Rate Tests between groups of sequences on a phylogenetic tree, BIOINFORMAT, 16(3), 2000, pp. 296-297
RRTree is a user-friendly program for comparing substitution rates between
lineages of protein or DNA sequences, relative to an outgroup, through rela
tive rate rests. Genetic diversity is taken into account through use of sev
eral sequences, and phylogenetic relations are integrated by topological we
ighting.
