Evaluating the effectiveness of ensemble voting in improving the accuracy of consensus signals produced by various DTWA algorithms from step-current signals generated during nanopore sequencing

A) The standard approach of displaying dtw warped plots does not provide a useful route for directly comparing the three DTWA consensus signals with each other because of the different consensus warped lengths. B) Normalizing the warped path lengths to one illustrates how close the DTWA consensus paths are to the Identity line for the Enolase study. This closeness emphasizes the fact that the consensus and original squiggles are essentially stretched versions of the underlying gold standard. C) Plotting the warped path differences from the Identity line shows that all three consensus signals differ in a similar way to the gold signal for the first half of the warp path, with the DBA (black) and SSG (green) being more similar to each other than with the MM consensus (red) in the last part of the warp path.
