Fig. 3From: Determining multiallelic complex copy number and sequence variation from high coverage exome sequencing dataEffects of sequencing centre and batch size on copy number clustering. The histograms show normalised sequence depth coverage data for the beta-defensin region for sub-Saharan African samples. X-axis values represent raw mean SVD-ZRPKM values a) BCM sequencing centre, n = 81 (15 YRI, 57 LWK, 9 ASW). b) BGI sequencing centre, n = 172 (26 YRI, 3 LWK, 25 GWD, 43 MSL, 47 ESN, 5 ASW, 23 ACB), with curved lines indicating the Gaussian mixture model used to call integer copy numberBack to article page
