LARGE-SCALE GENOME SEQUENCE PROCESSING

by Masahiro Kasahara & Shinichi Morishita (University of Tokyo, Japan)

Efficient computer programs have made it possible to elucidate and analyze large-scale genomic sequences. Fundamental tasks, such as the assembly of numerous whole-genome shotgun fragments, the alignment of complementary DNA sequences with a long genome, and the design of gene-specific primers or oligomers, require efficient algorithms and state-of-the-art implementation techniques. This textbook emphasizes basic software implementation techniques for processing large-scale genome sequences and provides executable sample programs.
