Hi,
My question is how can I select class intervals for synonymous and non synonymous rates to construct  an histogram? the data can´t be assigned as a normal distribution so how can I decide on the correct intervals in order to classify rates in a tree (to identify the average and the species that maybe significative different from the rest, perhaps accelerated)I am interested in assigning classes and identifying branches with different rates than the average.I want to map this differences on a chronogram (a molecular dated tree).
Thanks in advance,regards,
Amanda
