The following methods are defined, in addition to those on S4 formal classes documented elsewhere:
Quality assessment is performed on all files in directory
dirPath whose file name matches
pattern. The type of
analysis performed is based on the
type argument. Use
SolexaExport when all files matching
_export.txt files. Use
_realign.txt files. Use
Bowtie for Bowtie
MAQMapShort for MAQ
map files produced by
MAQ versions below 0.70 and
MAQMap for more recent output.
fastq for collections of fastq-format files. Quality
assessment details vary depending on data source.
dirPath is a list of objects, all of the same class and
typically derived from
ShortReadQ, on which quality
assessment is performed. All elements of the list must have names,
and these should be unique.
An object derived from class
contained in this object are meant for use by
