Multiple sequence alignment based upon statistical approach of curve fitting

Abstract

The main objective of our work is to align multiple sequences together on the basis of statistical approach in lieu of heuristics approach. Here we are proposing a novel idea for aligning multiple sequences in which we will be considering the DNA sequences as lines not as strings where each character represents a point in the line. DNA sequences are aligned in such a way that maximum overlap can occur between them, so that we get maximum matching of characters which will be treated as our seeds of the alignment. The proposed algorithm will first find the seeds in the aligning sequences and then it will grow the alignment on the basis of statistical approach of curve fitting using standard deviation. © 2009 Springer-Verlag Berlin Heidelberg.
