Thus, RS scores range from a maximum of 6.18 down to a below-zero minimum, which we cap at -12.36. RS scores will vary with alignment depth and level of …
WebNov 9, 2024 · original answer. The short answer is that you have to calibrate the branch lengths of the tree to yield the substitution rates per year you want. (Leave the topology alone.) Tree branch lengths are usually agnostic to chronological time (e.g. years). Instead it is very focused on whatever the model used to construct the tree is.
