Fig. 5From: Identification of SARS-CoV-2 variants using viral sequencing for the Centers for Disease Control and Prevention genomic surveillance programAssociation between Ct values and genome coverage. a Mean genome coverage of samples run on the two sequencing platforms is associated with baseline N gene Ct values of the samples. b Distribution of mean genome coverage achieved amongst samples from various Ct groups. c Ct values of 26.2 for NextSeq (red line) and 27.9 for NovaSeq (blue line) samples were identified as a selection resulting high quality (mean coverage > 100×, ambiguous nucleotide fraction in consensus sequence < 10%) sequencesBack to article page
