Segment counts (Y-axes) as a function of the threshold for the mean intensity value (X-axis). The solid lines are based on the Taylor data and the dashed lines are based on the FISH Oracle data. The red colored lines refer to segments in the minimal chromosomal region containing the gene PTEN (see also Figure 4) while the black colored lines refer to segments in the region 21q22.2/21q22.3 (see also Figure 5).
