Fig. 3From: decompTumor2Sig: identification of mutational signatures active in individual tumorsDifference between approximated and original STS. The histogram shows that the absolute difference between the matrix elements of the approximated matrix and the original matrix (i.e., |nearPD(STS)ij−(STS)ij|) is only a negligible fraction of the corresponding element of the original matrix (STS)ij. Data collected from the decomposition of 44 tumors with 15 signaturesBack to article page
