Description
Mask out low-quality bases in a DNA sequence prior to downstream analyses.
Usage
1
qualityMask(seq, max.err)
Arguments
seq
A QualityScaledDNAStringSet containing one or more sequences with quality strings.
max.err
Numeric scalar specifying the error probability threshold, above which bases are to be masked.
Value
A DNAStringSet containing masked DNA sequences.
All bases with error probabilities above max.err will be replaced with Ns.
