My genotyped data (represented by the star within the box and indicated by the black arrow) clusters with Central Sudanese groups in the principal component analysis of genome-wide genotyped data from Sudan and South Sudan published by Hollfelder et al. 2017.  

Principal Component Analysis (PCA) was performed using the smartPCA program (v13050) from the EIGENSOFT package (https://github.com/DReichLab/EIG). For this plot, I carefully recommend interpreting my data point (red star) representing the smallest sample size on the PCs.

Population descriptors used above are those originally used in the publication by Hollfelder et al. 2017, and they are based on the self-identified ethnicities of the participants collected during sample and questionnaire data collection.
