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

Dear Amanda,

I am not sure I understand your question. Generally speaking, you want to select enough bins to faithfully represent the underlying distribution: there are some pointers to be found at Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login

I don't know what you mean my assigning intervals to classify rates in a tree. Could you give me an example?
