Metagene profiles reveal genomic signals. Schematic of metagene analysis. Normalized arrays of quantitative data (e.g. ribosomal P-sites; top) are taken at each position in the maximal spanning windows of multiple genes. These arrays are aligned at a landmark of interest (here, a start codon), and the median value of each column (nucleotide position), is taken to be the average (bottom)
