High resolution CNV analysis using BAC aCGH and graCNV provide similar results. In IMR-32 cells, two amplicons on chromosome 2 at 67 and 69 Mb were inferred by segmentation analysis from graCNV data (C), but only the amplicon at 67 Mb from BAC aCGH data (A). In SK-N-SH/G cells, a deletion on chromosome 8 at 39.5 Mb was inferred from graCNV data (D), but not from BAC aCGH data (B). Physical positions are shown at the x-axis in units of 1000.
