A schematic overview of the AB3D peak detection algorithm. AB3D sequentially processes all candidate peaks from the maximum intensities to minimum intensities. To extract the XIC (the bottom) for a target peak A (the upper), all related peak information such as m/z, retention time and intensity were obtained by searching adjacent peaks in the range of m/z and retention time tolerances. B and C are the minimum and maximum m/z values respectively within the tolerance.
