From: PPINGUIN: Peptide Profiling Guided Identification of Proteins improves quantitation of iTRAQ ratios
Sample peptide profiles. Visualization of peptide quantitation profiles of the three different approaches employed (rows) demonstrated for 3 exemplary chosen proteins (columns). The three rows correspond to the applied method: first row = MASCOT, second row = X!Tandem and OpenMS, last row = PPINGUIN. Each individual plot shows ratio profiles of peptides uniquely assigned to the corresponding protein. For every ratio a box plot giving the lower quartile, median and upper quartile is drawn.
