Sensitivity as a function of mutation allele frequency for five sSNV-detecting tools. Given an allele frequency value f, the sensitivity of a tool T (either JointSNVMix, MuTect, SomaticSniper, Strelka, or VarScan 2) is calculated as: S T  = N T /N f where N f is the total number of sSNVs with sequencing depth ≥8, the number of alternate allele-supporting reads ≥2 in the disease sample, and an allele frequency less than f, and N T is the number of sSNVs that the tool T identified out of these N f point mutations.
