Hi Bruno,

You can transform the branches of your phylogeny using the estimated
parameters of OU models. Then, if those models describe the observed data
adequatly, the transformed tree should model the observed data as a
Brownian motion model. So you can use an ancestral state reconstruction
based on Brownian motion model. However, I do not know if that is the best
approach as optimum values would not be included into the reconstruction
