Ancient Latvians, comparing to modern people

New ancient Latvian genomes were figured in the new study from Jones et al.   Although all new genomes show rather low quality I have now made some dstat comparisons against modern populations.  Present-day Latvians were used as a fixed point.

PCA, trying to locate three ancient samples

And three dstat figuring samples MN2, HG2 and HG3.  Most of those samples have too low quality to give reasonable results, so I have now only three results.  I tried also map original fastq files and experienced it possible, giving more available SNP's, but I decided to not use them to ensure full comparability with the study.
