From: DBS: a fast and informative segmentation algorithm for DNA copy number analysis
Segmentation process with an actual data sample in DBS (using half copy numbers). a the segmentation process in the binary tree of ℤp. b plots the copy number of an actual sample, and shows the position and ℤp of the 12 true breakpoints, which correspond to these yellow nodes in Panel (a). In (b), the observed copy number signals are the ratios of the measured intensity of tumor-normal matched sample
