2016-10-31 Thread Gopal Murali
Dear list, I am tracing evolution of a binary trait on a phylogeny with 1500 tips. Since the trait is labile and scattered across the phylogeny (Fritz Purvis D= 0.45), I find it difficult to visually count the number of gains/origin of the trait in ancestral state reconstruction. Is there any
