Effects of variant caller on analyzing xenograft samples with MAPEX. (A–C) For all three calling algorithms and 34 xenograft samples (black dots), the number of raw variants called was strongly dependent on estimated mouse contamination. (D–F) After filtering with MAPEX, the number of calls was independent of mouse contamination for all three callers. Lines show linear regressions and shading denotes 95% confidence intervals
