Ancestral reconstruction

Ancestor gene reconstruction under constrains of amino acids changes (Zhang and Nei 1997; Zhang et al., 1998) First, Distance based Bayesian method applied for ancestral proteins reconstruction, than parsimony applied for codons inference. Universal genetic code only. Amino acid substitution models: LG (Le and Gascuel, 2008), WAG (Whelan and Goldman, 2001), JTT (Jones at al., 2001), CpREV (Adachi et al., 2000), MtREV (Adachi and Hasegawa, 1996), MtZoa (Rota-Stabelli al., 2009).

Correlation analysis

Phylogenetic statistic tests for evolutionary correlation between molecular and phenotypical characteristics R: ape You must enter quantitative phenotypical data for statistical analysis! Methods for comparative analyses of data in a phylogenetic framework: GEE (Paradis and Claude, 2002), Lynch (Lynch, 1991), Blomberg (Blomberg at al., 2003), Martins (Martins and Hansen, 1997), Grafen (Grafen, 1989), Pagel (Pagel, 1999), Brownian (Felsenstein, 1985).
