Figure Lengend Snippet: Coverage evenness of SARS‐CoV‐2 genome of multiplex PCR mix panels. (A) Coverage depth profile of six clinical samples for the 1K‐panel (~1000‐bp amplicons) and the ARTIC V3 primer panel (~400‐bp amplicons). Depth is in standard logarithmic scale, with 100‐fold denoted by the dashed line. Bold black lines denote median depth, and grey shadows indicate the minimum and maximum depths. Mean depth is defined as the average site depth on the targeted viral genome (excluding the 3′ and 5′ ends). (B) Two thresholds, >20% and >30% mean depth, were used to define regions of high coverage. Viral titers were quantified by the qRT‐PCR C t value of SARS‐CoV‐2 detection. (C) The correlation between coverage evenness and viral titers of samples for the 1K‐panel. The proportions of genome regions with a >20% mean depth for 49 clinical samples. SARS‐CoV‐2, severe acute respiratory syndrome coronavirus 2
