hello all
when i runned the scripts to clean the fastq data, it reported an
error.
but if i run it step by step, it has no problem
reads <- readFastq(fastqfile);
seqs <- sread(reads);
qual <- SolexaQuality(quality(quality(reads)))
that is the error place:
myqual_mat <- matrix(charToRaw(as.character(unlist(qual))),
nrow=length(qual), byrow=TRUE)
Error in .Call(.NAME, ..., PACKAGE = PACKAGE) :
negative length vectors are not allowed
Calls: trimRead ... matrix -> charToRaw -> unlist -> unlist -> .Call2
