Boxplot of the LLR distribution for different types of minor alleles (LLR > 3) observed in 6 runs of phiX174. Results from the strand bias and position rank sum tests are also shown, as follows, with the number of alleles in parentheses: CpG(15), minor alleles on CpG sites; p0(15), CpG after SB < 1 and PosRankSum > -3 filters; CT(20), C- > T mutations excluding CpG sites, where T is the minor allele; CT0(16), CT after filters; TC(14), T- > C mutations; TC0(10), TC after filters; CA(137), C- > A mutations; CA0(36), CA after filters; AC(26), A- > C mutations; AC0(24), AC after filters; GC(7), G- > C mutations; GC0(0), GC after filters. No A- > T minor alleles were observed
