Log-ratio and genotype sequences for chromosome 6 in paired samples from a CLL patient. The log-ratio sequence (top), genotype θ sequence (bottom), and the detrended cumulative plot for the "one deletion" indicator variable for SNPs on chromosome 6. Black and blue color refer to the normal and cancer cell sample taken from the same cancer patient. The largest run-of-homozygosity region is marked by red vertical lines. The copy number of 2 level log(2/2) = 0 and the copy number of 1 level log(1/2) = -0.693147 are marked in the log-ratio plot.
