Extended Data Fig. 3: ADMIXTURE ancestry assignment.
From: Indigenous Australian genomes show deep structure and rich novel variation
The clustering algorithm ADMIXTURE applied to the NCIG + PNG (masked) dataset (including related individuals) assuming K = 2 to K = 8 clusters (subpopulations) are represented in the data (See Methods). Clustering makes no reference to the sampling locations of the individuals and is based on genetic data alone. Individuals are listed along the x-axis, grouped according to their sampling location, with bars above reflecting their cluster assignment in the following manner: each inferred cluster is labelled by a colour and the proportion of bar assigned that colour represents the probability that the individual is assigned to that cluster. Colours were manually selected (post-hoc) for K = 7 to match the labels in panels 2 A and 2B of Fig. 2, and for other values of K the colouring scheme was merged or split as appropriate. Also shown are the cross-validation (CV) scores used for model selection.
