QC plots for 1,167 high quality samples from the Iberian cohort.

The 1,167 samples coming from Iberian population are used for benchmarking. rwGWAS QC showed the following QC statistics (A) Bar-plot for number of variants per sample, colored by variant type, (B) Barplot for number of variants per sample, colored by random assignment to cases (~1/3) or controls (~2/3), (C) Percentage of explained variance on first 9 PCA components, (D) Number of variants per gene in cases (x-Axis) and controls (y-axis). Each dot is one gene, while the red line shows the ratio of the number of cases and controls (1:2), (E) Histogram for number of mutations per sample, and (F) Projection on first 10 PCA components. Samples are colored by the center that performed the sequencing.
