Dear all, I just started to work with R and I have the following problem:I calculated a phylogenetic tree in RAmML. For further analysis, I need an ultrametric tree which
I wanted to make with the chronoMPL command in APE.However, the tree was not dichotomous and I used the multi2di(phylogeny, random = TRUE) function to resolve the
polytomies.Then I used the chronoMPL function chronoMPL(phy, se = TRUE, test = TRUE) to make the tree ultrametric.
However, the ultrametric tree looks really strange (see attachment). Do you have any suggestion?
Thank you in advance, Jacqueline
