Performance metrics of NGS technologies. (a-f) Error bars represent minimum and maximum values obtained from the four samples. (g-i) Venn diagram representation of false positive calls (g), false negative calls (h) and discrepant variants calls (i). The inset caption displays the color-coding of each NGS technology and overlaps: for Roche 454 (red), Illumina GA (yellow) and ABI SOLiD (blue). For each NGS platform the number of base calls with errors associated with specific sequence contexts is given (repeat = repetitive element). When two sequence contexts are present they are both listed.
