Sequence Alignment Tips from Brett Waterman
Brett Waterman's pioneering work on sequence alignment algorithms has revolutionized the field of bioinformatics. He has developed a set of tips and best practices that can help researchers improve the accuracy and efficiency of their sequence alignments.
Tip 1: Use the appropriate algorithm for the task. Waterman recommends using a global alignment algorithm, such as the Needleman-Wunsch algorithm, for aligning sequences that are closely related. For more distantly related sequences, a local alignment algorithm, such as the Smith-Waterman algorithm, is more appropriate.
Tip 2: Choose the right scoring matrix. The scoring matrix is used to assign scores to matches, mismatches, and gaps in the alignment. Waterman recommends using a scoring matrix that is appropriate for the type of sequences being aligned. For example, the BLOSUM62 matrix is commonly used for aligning protein sequences, while the PAM250 matrix is more appropriate for aligning DNA sequences.
Tip 3: Set the gap penalty appropriately. The gap penalty is used to discourage the introduction of gaps in the alignment. Waterman recommends using a gap penalty that is large enough to discourage unnecessary gaps, but not so large that it prevents the alignment of sequences with genuine gaps.
Tip 4: Use a seed and extend strategy. A seed and extend strategy can be used to improve the efficiency of sequence alignment. This involves finding a short, high-scoring seed region in the two sequences and then extending the alignment from the seed region.
Tip 5: Take advantage of multiple sequence alignments. Multiple sequence alignments can be used to improve the accuracy of sequence alignments. This involves aligning multiple related sequences simultaneously, which can help to identify conserved regions and improve the alignment of more distantly related sequences.
These tips can help researchers improve the accuracy and efficiency of their sequence alignments. By following these guidelines, researchers can obtain more reliable results from their sequence alignment analyses.
