Fig. 3: Population structure from both RGStrap and paired array genotype were consistent with self-reported ethnicities.
From: Direct inference and control of genetic population structure from RNA sequencing data

SNPs from the overlap of RNAseq variant calling results and HapMap3 were able to capture genetic structure separating self-reported ethnicities in Nepal when compared to the paired array genotypes, shown by the groupings in the PCA plots.
