Figure 3From: Sequence artefacts in a prospective series of formalin-fixed tumours tested for mutations in hotspot regions by massively parallel sequencing Low coverage samples have higher rates of C>T/G>A sequencing artefacts. For all FFPE samples (x-axis), values for coverage (blue) and the counts of C>T/G>A sequencing artefacts (red) are plotted on the same y-axis. There was an inverse correlation between coverage and C>T/G>A sequence artefacts (Spearman correlation, r = −0.24, p < 0.0001).Back to article page
