These regions may be caused by collapsed repetitive sequences in the reference genome assembly; they also have high read depth in assays such as ChIP-seq, and may trigger false positive calls from peak-calling algorithms. Excluding these regions from analysis of short-read alignments should reduce such false positive calls. </P> <H1>Methods</H1> <P> Pickrell <em>et al.</em> downloaded sequencing reads for 57 Yoruba individuals from the 1000 Genomes Project's low-coverage pilot data, mapped them to the Mar. 2006 human genome assembly (NCBI36/hg18), computed the read depth for every base in the genome, and compiled a distribution of read depths. They then identified contiguous regions where read depth exceeded thresholds corresponding to the top 0.001, 0.005, 0.01, 0.05 and 0.1 of the per-base read depths, merging regions which fall within 50 bases of each other.
