Read Classifications.

	% “Host” Reads	% “Graft” Reads	% “Ambiguous” Reads	% “Both” Reads	% “Neither” Reads
Tumor 40	52.30%	42.60%	3.00%	0.77%	1.30%
Tumor 42	39.50%	54.10%	3.50%	0.97%	1.90%
Tumor 44	64.70%	30.20%	2.90%	0.88%	1.34%
Average	52.2%	42.3%	3.1%	0.87%	1.51%

Proportion of reads Xenome classified to each category for all samples. The category “Host” refers to reads classified to the mouse reference genome while “Graft” refers to reads classified to the pig reference genome. The category “Both” refers to reads that match both mouse and pig reference genomes, “neither” represents reads that do not match either reference genome, and “Ambiguous” represents reads that are likely artifacts created during library preparation.
