Why does my posterior sample of trees created by MrBayes not contain branch lengths, when I specified savebrlens=yes?

12 February 2019 1 1K Report

I reconstructed a Bayesian phylogeny using MrBayes in CIPRES for further study in BayesTraits, but BayesTreesConverter returns an error because there are no branch lengths in the posterior sample of trees.

Checking the parameters in CIPRES, I specified 'yes' for savebrlens.

Is this normal? Could it be the large size of the alignment, 4 molecular markers for 1280 taxa?

Tiago Andrade Borges Santos

Did you try to use the sump and sumt commands? When these commands are used MrBayes automatically generates a consensus tree with branch length. In other hand, if you do the consensus from other software, the consensus tree usually is a cladogram, without branch length information.
