Fig. 4

p-value distributions for all four data sets. Each symbol corresponds to the comparison of one pair of samples in the respective data sets and its height represents the calculated probability that the two samples are derived from the same individual. Red diamonds indicate sample pairs from the same individual while blue circles indicate sample pairs from different individuals. For data set 4 data after exclusion of the failed quality control sample RNA09 is shown. The dashed line corresponds to the chosen threshold of 0.95 that discriminates pairings involving the same individual from pairings not involving the same individual in all four data sets
