Distribution of single nucleotide variants (SNVs) for each virus and for two Ebola virus strains. Distribution of single nucleotide variants (SNVs) for each virus and for two Ebola virus strains. For each plot, the y axis is the log10(SNV frequency) in order to display the range of low-frequency SNVs more accurately. (A) SNV analysis for each virus sample using its reference genome. Abbreviations: CDV, canine distemper virus; EBOV, Ebola virus; LACV, La Crosse virus; MV, measles virus; HRSV, human respiratory syncytial virus; VSV, vesicular stomatitis virus. (B) SNV analysis of 2,501,8050 filtered read-pairs revealed 223 SNVs in the reads that mapped to Ebola virus Mayinga with a frequency of ≥0.90, while there was only one SNV with a frequency of ≥0.90 in the reads that mapped to Ebola virus Kikwit.
