Figure 3: Errors across the genome in consensus sequences from the “Early Omicron” African dataset, split by sequencing technology and amplicon scheme.

Plots show the percent of consensus sequences with an error (y-axis), taking the maximum value in windows of length 50bp (x-axis). Error here is defined as where the consensus sequence has an A/C/G/T call, the read depth passes Viridian’s default filters (see methods), and the reads support a different A/C/G/T call. Results are shown for Viridian, the original assemblies, and for the ARTIC-ILM and ARTIC-ONT assembly workflows.
