Figure 1From: Bivariate segmentation of SNP-array data for allele-specific copy number analysis in tumour samplesTransformation from BAF to mBAF and then, into imBAF. A sample toy BAF signal is transformed to mBAF and then into imBAF. X-axis: probe index. Y-axis: B allele frequency (first) and B allele frequency mirrored along the 0.5 axis (second and third). Grey points represent homozygous SNPs within heterozygous regions.Back to article page
