Overlap between CNVs identified from Affymetrix and Illumina data. A) Counts of CNVs identified with different methods (see legend) from Affymetrix data are segregated according to their overlap with CNVs identified from Illumina data. The Illumina panel includes a subset of 239 CoLaus individuals. Affymetrix-based CNVs, which did not include at least one individual from the Illumina panel, were excluded from the analysis. Overlap is measured by the Jaccard coefficient, i.e. the ratio between the intersection and the union of two groups of CNVs. Expected counts from (1000 times) reshuffled data are shown in gray (extending over one standard deviation). Estimated p-values are indicated for significant enrichment (red) or depletion (blue), with respect to these controls. Non significant p-values (α > 1%) are shown in black. B) Percentage of changes between observed and expected counts from A. Error bars indicate +/- one standard deviation.
