CNV profiles of three experimental array-CGH data sets. Probe segmentation of (A) GBM31, (B) GBM29, and (C) β-globin small deletion array-CGH data. In all cases, the MCMC sampler was run for 1000 iterations. The first 100 samples were discarded as the 'burn-in' samples, and the mean and the standard deviation of each parameter were estimated from the rest 900 samples. The estimated means are plotted as a step function (the black line), and the estimated standard deviations are indicated as yellow boxes, each defined by mean ± 1.96 × standard deviation, which corresponds to a 95% credible interval.
