confused results of gamma

[sandyplus]

Dear @pblischak , In your paper "HyDe: A python package for genome-scale Hybridization detection", it suggests that the gamma is the probabilities of P2.

However, in your source code, it suggested that gamma is the probabilities of P1:

cpdef dict test_triple(self, str p1, str hyb, str p2):
        """
        Main method for testing a hypothesis on a specified triple.
        ((P1,Hyb),P2)::math:`\gamma` and (P1,(Hyb,P2))::math:`1-\gamma`.
        ...
        """

Moreover, our results suggested that the gamma in out-filtered.txt should be the probabilities of P1 (I calculated gamma in out-filtered.txt manually, and found that the gamma = 1 - (AABB-ABAB)/(AABB+ABBA-2*ABAB)).

I am confused about the "gamma" in filtered-out.txt. Would you mind give me any suggestion?

Best regards, Sandy
