Scoring results for identified spectra from a PeptideProphet fit in TPP. PeptideProphet output of sensitivity error analysis and figures of estimated mixture models. The bottom portion shows the fitted curves for different charges. The light blue curves represent the distribution of scores for incorrect identification, purple for correct identifications, and black the sum of the two distributions. The red vertical line also indicates the score for the identified spectra that we clicked on with its additional information at the bottom of the figure.
