Web15 mag 2024 · The Ti/Tv ratio of the detected SNPs was equal to 2.09, 2.07 and 2.05 using GATK, Graphtyper and SAMtools, respectively. Using GATK revealed four times more multiallelic SNPs (246,220) than either SAMtools or Graphtyper. WebThe Ti/Tv ratio is a critical metric for assessing the specificity of SNP calling [ 23 ]. The empirical Ti/Tv ratios are ~2.0 for genome-wide variants and ~3.0–3.3 for coding variants [ 18, 27 ].

The HiSeq4000, HiSeqX10, and NovaSeq6000 showed higher adapter contamination rates than other platforms, probably due to longer sequence length (151 bp). WebIn this context, the transition-transversion ratio (Ti/Tv) is commonly used as an additional quality check. In case of IR experiments, this is problematic when Ti/Tv itself might be influenced by IR treatment. the hypotenuse of a triangle is 19cm long
