In the "Experiment" column, the estimated subpopulation percentages from the 6 experiments are shown: Two pure tumor samples (S1 and S2), and four samples with tumor mixed with 15 or 30% normal cells. The best fit for S1 is three subpopulations, whereas it is two for "S1 with 15%" and "S1 with 30%"; therefore we show results for both two and three subpopulations to facilitate comparison. The remaining three columns contain percentages estimated from the Experiment column; e.g. to estimate the percentages of the sample with 85% malignant cells and 15% normal cells ("S2 with 15%") from the sample S2 do (0.62·85 + 15, 0.24·85, 0.14·85) = (68, 20, 12).
