In decompTumor2Sig: Decomposition of individual tumors into mutational signatures by signature refitting

Description

Examples

### get Alexandrov signatures from COSMIC
signatures <- readAlexandrovSignatures()

### load reference genome
refGenome <- BSgenome.Hsapiens.UCSC.hg19::BSgenome.Hsapiens.UCSC.hg19

### read breast cancer genomes from Nik-Zainal et al (PMID: 22608084) 
gfile <- system.file("extdata",
         "Nik-Zainal_PMID_22608084-VCF-convertedfromMPF.vcf.gz", 
         package="decompTumor2Sig")
genomes <- readGenomesFromVCF(gfile, numBases=3, type="Alexandrov",
         trDir=FALSE, refGenome=refGenome, verbose=FALSE)

### compute exposures
exposures <- decomposeTumorGenomes(genomes, signatures, verbose=FALSE)
