Identifying cis-regulatory elements for transcription factors through ChIP-seq experiments is a popular method recently. In real applications, often a top fraction (e.g., according to P-values) of all discovered peaks are scanned to discover DNA motifs. However the optimal ranking and thus the selection of these top fraction peaks is not well studied. A mixture model of Gaussian and Uniform Distribution of the ChIP-seq peaks is proposed in this work, which in combination with the Poisson enrichment P-values provides a much improved ranking for the purpose of DNA motif discovery. This method is expected to be useful in decoding the cis-regulatory mechanisms underlying the gene regulatory network
