The errors are based on estimates from 3574 SNPs which could be analyzed by all methods.

*Data used for normalization: "our" = 34 individuals analyzed in our lab, "Brohede" = 26 individuals analyzed in the lab of Brohede et al. [1], "web" >3000 individuals analyzed in the lab of Caig et al. [9], files are available under [15].
