Comparison of Cytosine Deamination patterns in the 5′ end of sequencing reads between the samples from the Leprosarium (yellow dotted lines) and UDD (red dotted lines) burial sites with a ~5,000 year old Scandinavian hunter-gatherer and a 100 year old Australian Aboriginal.
The range of C to T changes suggest the authenticity of the data.
