Agreement between CN calls made by Birdsuite and qPCR. Birdsuite CN calls were compared to qPCR copy number calls at 18 distinct chromosomal regions on 10 chromosomes. A total of 387 data points were considered in the analysis. At CN = 0, 12/12 samples agreed, at CN = 1, 48/55 samples agreed, at CN = 2, 313/319 samples agreed and at CN = 3, 0/1 sample agreed. Results are expressed as % agreement between any the two methods of CN call determinations.
