We investigate off-line dictionary oriented approaches to DNA sequence compression, based on the Burrows-Wheeler Transform (BWT). The preponderance of short repeating patterns is an important phenomenon in biological sequences. Here, we propose off-line methods to compress DNA sequences that exploit the different repetition structures inherent in such(More)
This paper explores two techniques for on-line exact pattern matching in files that have been compressed using the Burrows-Wheeler transform. We investigate two approaches. The first is an application of the Boyer-Moore algorithm (Boyer & Moore 1977) to a transformed string. The second approach is based on the observation that the transform effectively(More)
