Decomposition-based peak identification (DPI)

This tool identifies a set of reference peaks in in genome-wide TSS (transcription starting site) profiles obtained from diverse range of biological states. In particular, this is developed for the FANTOM5 project (Nature 507, 462-467, 2014 and its related papers) that produced CAGE profiles in more than one thousand of biological states in human and mouse, and the analysis results have been available at http://fantom.gsc.riken.jp/5/ as well as the article above.

In general, I recommend to use the FANTOM5 peak set for CAGE analysis, rather than runnning this tool for your own data, so that you can compare your results with others. I would recommend to run this tool to identify a set of TSS peaks in other organisms than human and mouse, or very unique biological conditions not included in the FANTOM5 sample collecttion.
