Description: Parametric Time Warping aligns patterns, i.e., it aims to
        put corresponding features at the same locations. The algorithm
        searches for an optimal polynomial describing the warping. It
        is possible to align one sample to a reference, several samples
        to the same reference, or several samples to several
        references. One can choose between calculating individual
        warpings, or one global warping for a set of samples and one
        reference. Two optimization criteria are implemented: RMS (Root
        Mean Square error) and WCC (Weighted Cross Correlation). Both
        warping of peak profiles and of peak lists are supported. A
        vignette for the latter is contained in the inst/doc directory
        of the source package - the vignette source can be found on the
        package github site. See `citation("ptw")` for more details.
