TL;DR
Two techniques for alignment of profiles, namely dynamic time Warping (DTW) and correlation optimized warping (COW) were tested and compared and the attention was focused on chromatographic and spectroscopic profiles.
Abstract
The alignment of analytical signals is an important preprocessing step when further analysis (e.g. PCA) requires the same lengths of all of them. Two techniques for alignment of profiles, namely dynamic time warping (DTW) and correlation optimized warping (COW) were tested and compared. The attention was focused on chromatographic and spectroscopic profiles. Simulated and two sets of real data were studied in this study.

The method presented uses the entire chromatographic data matrices and does not require any preprocessing e.g., peak detection, and relies on piecewise linear correlation optimised warping (COW) using two input parameters which can be estimated from the observed peak width.
