seqTools-package
SeqTools: Bioconductor package for analysis of FASTQ and fasta files.
Fastqq-class
Class
"Fastqq"
phredDist
phredDist: Global relative content of Phred values in Fastqq objects (or subsets).
countDnaKmers
countDnaKmers: Counting k-mers in DNA sequence.
ascii2char
ascii2char: Converting ASCII encoded values to character values.
meltDownK
meltDownK: Condensing DNA k-mer count data to lower k-value (i.e. shorter DNA motifs).
plotKmerCount
plotKmerCount: Creation of plots DNA for k-mer counts from Fastqq objects.
plotNucFreq
plotNucFreq: Plots the position wise relative nucleotide content for nucleotides 'A','C','G','T'.
mergedPhred
mergedPhred functions: Retrieving and plotting of phred quantities from whole
Fastqq
