1 Description of the dataset and the aim of the analysis

In a recent study we have identified thousands of quantitative trait loci (QTLs) for different histone marks using individuals from the Yoruban (YRI) population [2]. In our case, histone (h)QTLs are SNPs for which the genotype correlate with the variation of histone H3K27ac signal within a H3K27ac peak. Here we will investigate how many of these previously identified hQTLs show allele-specific binding in individuals from a different population (CEU; European).

The example dataset consists of the following files:
