+**PEAKachu**
+
+PEAKachu is a tool for the accurate mapping of RBP binding sites based on CLIP-seq and RIP-seq data.
+PEAKachu uses signal and control libraries (ideally more than three each) to detect binding sites.
+It implements two peak calling approaches
+
+**adaptive**
+
+The adaptive approach applies a three-step procedure to detect regions that are significantly enriched over controls.
+
+- blockbuster is applied to the pooled libraries to combine similar sets of reads into blocks
+- blocks are decomposed into peaks by iteratively applying a block merging heuristic
+- peaks with significant enrichment of signal over control libraries are determined using DESeq2
+
+**windowed**
+
+The windowed approach subdivides the genome into overlapping regions.
+After filtering of lowly expressed regions and library normalization (either using manual size factors, TMM, or DESeq2), this approach determines significantly enriched windows using eiterh DESeq2 or repeated G-tests of goodness-of-fit.
