GCxGC-MS alignment algorithm

This algorithm is used to align GCxGC-MS chromatograms according to the method of Zushi et al., 2017. The algorithm is programmed in Matlab, and it represents an adaptation of a previous method to multivariate detectors. For univariate detector data, please refer to the method of: Gros et al., 2012. That you can obtain at: To learn how to use the program, see the documentation for users.
