WebMar 26, 2024 · The Burrows-Wheeler Transform (BWT) has become an essential tool for compressed text indexing. Computing it efficiently and within little space is essential for the practicality of the indexes that build on it. A recent algorithm (Munro, Navarro & Nekrich, SODA 2024) computes the BWT in O (n) time using O (nlgσ) bits of space for a text of ...

WebIn this paper, an efficient approach: WIT for reference genome indexing and reads alignment using Burrows-Wheeler Transform (BWT) and Wavelet Tree (WT) is proposed. Both exact and approximate alignments are possible by it. Experimental work shows that the proposed approach WIT performs the best in case of protein sequence indexing.
