The Bowtie sequence-alignment algorithm uses advanced data structures to help data analysis keep pace with data generation. In this month s Genome Biology Langmead and colleagues 1 present the Bowtie algorithm. Bowtie is designed to align large numbers of relatively short DNA sequencing reads to an entire reference genome. It does so by first taking the reference genome assembly and changing the order of the sequence using something called the Burrows-Wheeler Transform. Why is this useful Speed is the best answer Bowtie is more than 30 times faster than other published tools designed to do the same task. Let s step back and see why the need for speed in our analysis algorithms is greater now than at any time in the genomic age. Over the past three years massively high-throughput sequencing often called next-generation sequencing has developed from a few beta devices in key genome centers to a large installed base in research labs around the world. The success of sequencing machines such as Illumina Solexa ABI SOLiD and 454 FLX has facilitated the development of sequencing as a general-purpose experimental tool for many biological applications. The range of possible uses is rapidly establishing DNA sequencing as the microscope of modern biology. The scale of data generation is amazing for example in the course of its pilot phase the 1000 Genomes Project 2 has already generated almost 2 000-fold total coverage of the human genome from 180 individual samples an amount orders of magnitude larger than the .
