Figure 5From: MassSorter: a tool for administrating and analyzing data from mass spectrometry experiments on proteins with known amino acid sequencesScreenshot of an accuracy plot for five PMF experiments of a protein. A peptide that consistently showed aberrant accuracies in the range of -40 to -60 ppm is boxed. Despite the hit within the accepted accuracy limit, the aberrant behavior strongly indicates that this is not the suggested peptide.Back to article page
