Peak alignment using restricted edit distances

Research output: Contribution to journalArticleScientificpeer-review

Abstract

A peak is a pair of real values (x, y), where x is the time when peak of height y is registered. In the peak alignment problem, we are given two sequences of peaks, and our task is to align the sequences allowing some basic edit operations on the peaks. We study an instance of the peak alignment problem that arises in the analysis of Mass Spectrometry data in Systems Biology. There the measurement technique guarantees that two peaks (x, y), (x', y') can only be considered the same if x is close enough toe, and y is close enough to y'. We review some methods to do alignment under such restrictions on matches. (C) 2007 Elsevier B.V. All rights reserved.
