    """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."""
