Hello, I was wondering if it is possible to estimate branch lengths on a fixed topology from a matrix of nuclear or mitochondrial DNA data. I used to do this in PAUP and would very much like to have an alternative in R. In PAUP one loaded a matrix of molecular data and a topology (without branch lengths) with identical species coverage, then branch lengths were estimated using maximum likelihood (could also use parsimony) and given settings for the substitution model. Any tips would be appreciated!
