Wavelet-based segmentation of S. aureus tiling signal. Visualization of S. aureus tiling microarray signal along 200 kb of NCTC8325 genome. Each dot corresponds to a probe of the forward strand (top) and reverse strand (bottom) for sigB mutant and 15981 wild-type normalized signals. The superimposed pulse signal represents the segmentation obtained using ZCL. The parameters of the analysis are described in the Results and discussion section of the manuscript.
