Figure 5.

The box plots of the break point position estimates (first column) and the copy number estimates (second column) of CNVs with different copy number: 0, 1, 3 and 6 (from the first row to the last row). The coverage is fixed to 5, and the single copy length is fixed to 6 kbp. The horizontal red dotted lines indicate the ground truth values b; the red solid lines indicate the median value; and the red pluses indicate outliers. It indicates that our proposed CNV-TV method gives more robust estimates of both the break point position and copy number than other methods for CNVs of different copy numbers.
