Fig. 5: Frequency and genome location of single nucleotide variants detected in SA14 and vaccine derivatives.

RNA was extracted and sequenced using Illumina methods. LoFreq software was used to detect SNVs in SA14 (A), SA14-14-2 (B), SA14-5-3 (C) and SA14-2-8 (D) samples. Dotted lines represent 50% of the population at which an SNV would become the consensus nucleotide and 1% of the population. An SNV frequency cutoff was applied at 0.05% frequency.
