The distributions of the endogenous peptides from proteins with three or more independent correlations to the same protein accession by X!TANDEM. Panels a the scatter plot of log₁₀ precursor intensity values versus precursor m/z; b the scatter plot of the log₁₀ distribution of precursor intensity values versus peptide mass [M + H]⁺; c the sorted distribution of log₁₀ intensity values; d the quantile plot of precursor log₁₀ intensity values; e the sorted distribution of calculated peptide mass [M + H]⁺; f the quantile plot of peptide [M + H]⁺; g the sorted distribution of the peptide delta mass; h the quantile plot of the delta mass; i the relationship between delta M + H versus peptide log₁₀ p-value
