Smith-Waterman Algorithm and Systolic PE Array The Smith-Waterman algorithm is a well-known dynami c programming algorithm for performing local sequence alignment for determining similar regions between two DNA or protein sequences. The algorithm was first proposed by T. Smith and M. Waterman in 1981. Nowadays, it is still a core algorithm of many applications [18] The Smith-Waterman algorithm 7 can be used to find the best alignment by applying the following conventions. A weight/score is assigned to each of the formed pairs of nucleotides: + w if they are identical, − y if there is a mismatch or a gap. The score of a particular alignment is the sum of the individual scores. Assuming that we have two sequences, S and T, of length N and M, respectively.

B ecause I am currently working with Local Sequence Alignment (LSA) in a project I decided to use the Smith-Waterman algorithm to find a partially matching substring in a longer substring . Since I am coding in Python, I was sure there were dozens of implementations already, ready to be used. I found a few indeed, namely here and here. However, the first implementation is incomplete, because it only includes calculating the scoring matrix and not the backtracing. I did not test.

Biologically, this means that the weights or scores assigned to. Today, the Smith-Waterman alignment algorithm is the one used by the Basic Local Alignment Search Tool (BLAST) which is the most cited resource in biomedical literature. In this adaptation, the alignment path does not need to reach the edges of the search graph, but may begin and end internally. In order to accomplish this, 0 was added as a term in the score calculation described by Needleman.


The Smith-Waterman algorithm is an algorithm that calculates the optimal local alignment score ( similarity score) or the optimal local alignment between two sequences.A sequence alignment is a sequence of edit operations (such as character replacement, insertion, deletion) that convert one sequence into the other. The individual operations have a score and the alignment score is defined as.

Smith-Waterman Algorithm - Local Alignment of Sequences

The Smith-Waterman algorithm provides optimal local alignment for the sequence pairs. It requires a large amount of processing time due to its high computational complexity, which is proportional to the product of the length of two sequences. To improve the performance of the Smith-Waterman algorithm, it is parallelized in GPU [10,11,12,13] The Smith-Waterman (SW) algorithm based on dynamic programming is a well-known classical method for high precision sequence matching and has become the gold standard to evaluate sequence alignment software. In this paper, we propose fine-grained parallelized SW algorithms using affine gap penalty and implement a parallel computing structures to accelerating the SW with backtracking on FPGA. The Smith-Waterman algorithm is a computer algorithm that finds regions of local similarity between DNA or protein sequences. Keywords: DNA; protein; sequence alignmen Smith-Waterman algorithm which is based on dynamic programming provides a high sensitivity but it makes the algorithm more computationally intense with such data de-pendencies that restrict it to easily scale for parallel impli-mentations [3] [4] . The time complexity of this algorithm for comparing two sequences is O(mn), where m and n are the lengths of the two sequences being compared. In this paper, we present the implementations of the Smith-Waterman algorithm for both DNA and protein sequences on the platform. The main features include: (1) we bring forward a multistage PE (processing element) design which significantly reduces the FPGA resource usage and hence allows more parallelism to be exploited; (2) our design features a pipelined control mechanism with uneven stage.

The algorithm used to compute the optimal local alignment is the Smith-Waterman (Smith and Waterman, 1981) with the Gotoh (1982) improvements for handling multiple sized gap penalties.The two sequences to be compared, the query sequence and the database sequence, are defined as Q = q 1, q 2 q m and D = d 1, d 2 d n.The length of the query sequence and database sequence are m = ∣Q. BACKGROUND: The Smith-Waterman algorithm is known to be a more sensitive approach than heuristic algorithms for local sequence alignment algorithms.
