I am interested in comparing branch lengths from trees made with IQTree to the MCMC-determined divergence times found between nodes of the same branch so I can calculate the simple ratio which would represent the #amino acid substitutions/site/100 Mya.
Has anyone done this? Perhaps written a script that I can use?
I can extract this by hand, but finding the same nodes in the 2 trees is difficult, even for trees with 200 tips!
Thx in advance!
