Additional file 1. Figure S1: DNA copy numbers of three cases. Copy-number plots were generated using methylation classifier data. Dot plot indicates copy number of each location. Green or red dots indicate that the log2 copy number ratio is higher or lower than zero, respectively. The x-axis indicates location. The y-axis indicates the log2 copy number ratio. Dotted line indicates threshold of significant amplification (0.35) or deletion (−0.35).
