Table 6 Peptide (PMF) peak-list and peptide fragment ions (MS/MS) peak-list properties. MME – mass measurement error. The rows 1 and 4 provide &five-number summary and the mean of the peak-lists lengths (number of peaks in peak-list) in the dataset. Rows 2,3 (PMF) and 5,6 (MS/MS) provide the five-number summary and the mean of the number of matches observed if comparing within and between cluster peak-lists pairs. Min. – minimum, 1st Qu. – first quartile, 3rd Qu. – third quartile, Max. – maximum
