We used the compendium as a benchmark for motif discovery tools. 2) We developed Amadeus, a highly efficient, user-friendly software platform for genome-scale detection of novel motifs, applicable to a wide range of motif discovery tasks. Amadeus improves upon extant tools in terms of accuracy, running time, output information and ease-of-use, and is the only program that attained a high success rate on the metazoan compendium. 3) We demonstrate that by searching for motifs based on their genome-wide localization or chromosomal distributions (without using a pre-defined target set), Amadeus uncovers diverse known phenomena, as well as novel regulatory motifs.
