Closed:Calculate dn ds ratio for the whole tree with python

Question

[Darrill]

Hello, I'm using the codeml application with the python package ete3 in order to calculate the dN/dS ratio of my trees, but it appears that there is no possibility to calculate a such ratio for all the three, only for the branches.

Does someone know why ? And if so if there are other package in order to calculate a global dN/dS for the whole tree?

Thank you for your help.

Here Is an exemple where I succeed with ete3 to calculate the dN/dS ratio (in red) for all branches: But what I would like is to get a global dN/dS for all the tree (the cluster) and not just for each branche .
