data(FoxA1_chr19)matrix with the coverages for the genomic interval corresponding to the gene body of a certain set of genesCoverageView function named cov.matrix and setting the extend parameter to 1000 and the bin\_width paremeter to 10. The BED format coordinate file was passed to the function through the coordfile argument and contained the transcription start sites (TSS) of the genes that had a valid MACS peak in the region spanning 2500 nucleotides on each side of the TSS. All peaks, regardless its false discovery rate, were considered. For illustrative purposes only the genes located in the chr19 were analyzed.
