Density plot of the relative distance from the positions with maximal scores to the annotated TSS. The dot curve is based on the prediction from the ChIP-chip experiment. The solid curve is for CoreBoost. The dashed and the dot-dashed curves correspond to McPromoter and Eponine, respectively. The right figure is a zoomed in version of the left one. ChIP, chromatin immunoprecipitation; TSS, transcription start site.
