Fig. 4

The effect of quality score and coverage. a Barplot of coverage in different error-correction schemes, before and after quality score filtering. The labels, ec1f, ec1r, ec2, ec3f, ec3r, and ec4 represent Scheme 1 forward reads, Scheme 1 reverse reads, Scheme 2, Scheme 3 forward reads, Scheme 3 reverse read, Scheme 4, respectively. b The errors rate correlation between original data and quality score filtered data. The dashed lines represent complete identical error rates before and after quality score filtering
