Overview of the mutation spectrum, for different sets of mutations called.

Mutations were called with different values of the threshold frequency for detecting mutations (τ), noted as percentages here, and for different values of the maximum number of lineages in which a mutation could occur before being excluded from the analysis (ψ). The number of transitions (transit.) and transversions (transver.) observed is noted, and below the transition to transversion ratio and its confidence interval (CI) are given.
