%description
Variable Penalty Dynamic Time Warping (VPdtw) for aligning chromatographic
signals. With an appropriate penalty this method performs good alignment
of chromatographic data without deforming the peaks (Clifford, D., Stone,
G., Montoliu, I., Rezzi S., Martin F., Guy P., Bruce S., and Kochhar
S.(2009) <doi:10.1021/ac802041e>; Clifford, D. and Stone, G. (2012)
<doi:10.18637/jss.v047.i08>).
