Table 2: Description of the used datasets. All the datasets are NGS sequences (reads). The third column includes the number of sequences in millions, and the third column is the data size in GB. There are four sets of the African human genomes of different sizes. The final dataset (130 G) is the original complete one. The three previous ones (1 G, 10 G, 40 G) are subsets of it.
