The Modern Human Variants track shows variant calls made from sequence
reads of eleven individuals mapped to the human genome. The purpose of
this track is to put the divergence of the Denisova genome into
perspective with regard to present-day humans.
DNA was obtained for each of ten individuals from the
CEPH-Human Genome Diversity Panel (HGDP):
DNA was also extracted from a Dinka individual from Sudan (DNK02).
To minimize biases due to instrument variability, the samples were pooled
for sequencing, using four barcoded libraries per sample.
The paired-end reads were aligned to the human genome
using the Burrows-Wheeler Aligner and potential PCR duplicates
were filtered using
Genotype calls for single nucleotide variants and small insertions and
deletions were made using the Unified Genotyper from the
Genome Analysis Toolkit (GATK), with an additional iteration
using a modified reference genome in order to reduce reference bias
