      """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."""
