Hello, 

I am using somaticsignatures to determine the mutation signatures post NMF decomposition in my samples.

When I use the following commands:

snpvr = with(snp, VRanges(seqnames = Chromosome, ranges = IRanges(Start_position, End_position), ref = Reference_Allele, alt = Tumor_Seq_Allele2, study = Tumor_Sample_Barcode, refCount = (Coverage-Count), altCount = Count ))
snpvr_ucsc = ucsc(snpvr)
sort(table(snpvr_ucsc$study), decreasing = TRUE)
snpvr_motifs = mutationContext(snpvr_ucsc, BSgenome.Hsapiens.UCSC.hg19, unify = TRUE)
snpvr_mm = motifMatrix(snpvr_motifs, group = "study", normalize = FALSE)


n_sigs = 6
gof_nmf = identifySignatures(snpvr_mm, n_sigs, decomposition = nmfDecomposition)

plotSamples(gof_nmf)

 

I am getting the following error message:

Error in if (debug) { : argument is of length zero

 

Can you please let me know what might be the problem?

 

Thanks!

Can you please provide a full, reproducible example of your problem ( see https://bioconductor.org/help/support/posting-guide )?

Hi Julian,

Since this is the only error I get, and no plots are made, I am not sure how to provide you with more details.

The error "Error in if (debug) { : argument is of length zero"

is seen with all Plot functions in SomaticSignatures.

Using sessionInfo()  I have the output below, incase I am using the wrong version of any of the packages.

Hi,
You are running a very outdated version of Bioconductor which also means that none of the installed packages has been supported for over a year. Could you consider upgrading your Bioconductor installation, as described in the help pages, and see if the issue still persists?

Updating Bioconductor helped solve the problem.

Thanks!
