Extended Data Fig. 4. Freyja more accurately estimates virus abundance, with fewer false positives.

A-B. Estimated vs expected fraction of each lineage in the mixture (n = 95, one sample per mixture type). The Kallisto-based approach from Baaijens et. al shows a wider range of estimates for each known mix fraction, and generally underestimates the fraction. C. False positives with abundance greater than 0.5%.
