PREFIX BURROWS-WHEELER TRANSFORMATION WITH FAST OPERATIONS ON COMPRESSED DATA

摘要

The Prefix Burrows-Wheeler Transform (“PWBT”) is described to provide data operations on data sets even if the data set has been compressed. Techniques to set up a PWBT, including an offset table and a prefix table, and techniques to apply data operations on data sets transformed by PWBT are also described. Data operations include k-Mer substring search. General applications of techniques using PWBT, such as plagiarism searches and open source clearance, are described. Bioinformatics applications of the PWBT, such as genomic analysis and genomic tagging, are also described.
