Additionally, whilst Refphase’s ability to infer SCNA events at low tumour purities exceeds that of single-sample copy number calling methods ( Fig 4F ), even with Refphase, we observe a moderately significant association between the range of purities within a tumour (‘Tumour Purity Difference’) and the degree of SCNA subclonality (LME coefficient = 0.28, LME ANOVA p = 0.04, adjusted, S9B Fig ), indicating that tumour purity may interfere with the estimation of SCNA clonality.
