Figure 4

The mean segmentation calculated from the analysis of SK-BR-3 compared with (A,B) the normal reference and (C,D) CHTN159. In all panels, the Y-axis is the value of the mean segment for each probe in log scale. In A and C, the X-axis (Mean Segment Index) is in ascending value of the assigned mean segment. In B and D, the X-axis (Gen Index) is the genomic index, as described above. Plotted on top of the mean segment data is a copy number lattice extrapolated from the array data using formulas within the text (horizontal lines). The calculated copy number for each horizontal line is to the right of the lattice.
