Nested Class Summary

static class

Alignment.AlignmentType

Constructor Summary

Alignment(Alignment.AlignmentType type, Costs costs)
Creates a new Alignment instance that aligns the sequences s1 and s2 using the costs defined in costs.

Alignment(Alignment.AlignmentType type, Costs costs, int offDiagonal)
Creates a new Alignment instance that aligns the sequences s1 and s2 using the costs defined in costs and a banded version of the alignment algorithm.

Method Summary

PairwiseStringAlignment	getAlignment(Sequence s1, int startS1, int endS1, Sequence s2, int startS2, int endS2) Computes and returns the alignment of s1 and s2 (Alignment(AlignmentType, Costs)).
PairwiseStringAlignment	getAlignment(Sequence s1, Sequence s2) Computes and returns the alignment of s1 and s2 (Alignment(AlignmentType, Costs)).

Parameters:

type - the type of the alignment

costs - the costs

Alignment

public Alignment(Alignment.AlignmentType type,
                 Costs costs,
                 int offDiagonal)

Creates a new Alignment instance that aligns the sequences s1 and s2 using the costs defined in costs and a banded version of the alignment algorithm.

Parameters:
