PRI-CAT (Muino et al 2011; http://www.ncbi.nlm.nih.gov/pubmed/21609962 ) is a user-friendly web-tool for the analysis of plant ChIP-seq experiements. Starting with the raw sequences, the user will obtain the DNA binding maps in a wiggle file format, as well as, the potential target genes of the studied transcription factor. A DAS server was implemented for storage of the resulting DNA binding maps. At the moment, more than 30 binding maps are avaliable. All of them can be visualized with a DAS-compatible genome browser (eg: IGB), or download directly to the GALAXY framwork for futher analysis.
