est_mixture             It is a function that takes the LRR obtained
                        from SNP array data and returns the estimated
                        tumor and normal proportions. Currently, the
                        function can performs the proportion
                        estimations by assuming the number of tumor
                        clones to be 1 or 2 or 3. The normalization
                        step is not required and the normalization
                        constant will be returned by this function. The
                        function will output two sets of solutions
                        corresponding to the top 2 optimal solutions
                        based on the posterior distribution. You can
                        choose according to your expertise the one that
                        is more reasonable.
est_mixture_wgs         It is a function that takes the count data
                        obtained from whole genome sequencing (WGS)
                        data and returns the estimated tumor and normal
                        proportions. Currently, the function can
                        performs the proportion estimations by assuming
                        the number of tumor clones to be 1 or 2. The
                        normalization step is not required and the
                        normalization constant will be returned by this
                        function. The function will output two sets of
                        solutions corresponding to the top 2 optimal
                        solutions based on the posterior distribution.
                        You can choose according to your expertise the
