  We investigate usage of dynamic time warping (DTW) algorithm for aligning raw
signal data from MinION sequencer. DTW is mostly using for fast alignment for
selective sequencing to quickly determine whether a read comes from sequence of
interest.
  We show that standard usage of DTW has low discriminative power mainly due to
problem with accurate estimation of scaling parameters. We propose a simple
variation of DTW algorithm, which does not suffer from scaling problems and has
much higher discriminative power.
