WebThe general time reversible distance is the most general transformation that can be applied to a pair of DNA sequences which aims to return the expected average number of substitutions per site. This was first described by Lanave et al. (1984), and in a different form by Tavare (1986) and Rodriguez (1990). http://ecite.utas.edu.au/77706/
