+Kraken is a system for assigning taxonomic labels to short DNA
+sequences, usually obtained through metagenomic studies. Previous
+attempts by other bioinformatics software to accomplish this task have
+often used sequence alignment or machine learning techniques that were
+quite slow, leading to the development of less sensitive but much faster
+abundance estimation programs. Kraken aims to achieve high sensitivity
+and high speed by utilizing exact alignments of k-mers and a novel
+classification algorithm.
+
+In its fastest mode of operation, for a simulated metagenome of 100 bp
+reads, Kraken processed over 4 million reads per minute on a single
+core, over 900 times faster than Megablast and over 11 times faster than
+the abundance estimation program MetaPhlAn. Kraken's accuracy is
+comparable with Megablast, with slightly lower sensitivity and very high
+precision.
