Figure 4From: An iterative block-shifting approach to retention time alignment that preserves the shape and area of gas chromatography-mass spectrometry peaksAn example of iterative peak matching. A 700-scan region of S TIC is shown which has 7 detected peaks. Peaks are assigned to blocks at the start of each iteration, with blocks shown as boxes of height matching the iteration number. Intensities are log transformed for a better display of weak signals.Back to article page
