Abstract :
The paper presents a new spectrum-based alignment method that is able to precisely adjust the retention times of Gas Chromatography/Mass Spectrometry data so that corresponding scans of two samples can be chosen for comparison purposes. It includes the ability to do precise alignment within fractions of a scan; this is equivalent to doing sub-pixel registration of images.
