Patterns retrieved from mining the top 10 frequent itemsets (using the mtv algorithm) from unexplained peaks in a peptide mass fingerprint datasets. Each row corresponds to a pattern. Masses present in the pattern are indicated as dots, with a color representing their origins (red = trypsin, blue = matrix cluster, black = unknown). Results for three different support thresholds (0.5, 0.25 and 0.125) are shown.
