export file formats.
o Don't allow R memory to be released prematurely when processing
old bowtie file formats / creating external pointers.

specified by the caller (typically mode="a")
CHANGES IN VERSION 1.23
-----------------------
NEW FEATURES
o alphabetScore,PhredQuality-method implemented
o reverse, reverseComplement methods for ShortReadQ objects
o srlist, to access SRList data as a base R list.
SIGNIFICANT USER-VISIBLE CHANGES
o readFastq qualityType="Auto" chooses base-64 encoding when no

argument
CHANGES IN VERSION 1.21
-----------------------
NEW FEATURES

o alphabetByCycle supports amino acid string sets
CHANGES IN VERSION 1.19
-----------------------
SIGNIFICANT USER-VISIBLE CHANGES
o qa(..., type="fastq") uses a sample of n=1000000 reads by
default, rather than then entire file; use sample=FALSE to
revert to previous behavior.
NEW FEATURES
o encoding,FastqQuality and encoding,SFastqQuality provide a
convenient map between letter encodings and their corresponding
integer quality values.
o filterFastq transforms one fastq file to another, removing reads
or nucleotides via a user-specified
function. trimEnds,character-method & friends use this for an
easy way to remove low-quality base.
BUG FIXES
o writeFastq successfully writes zero-length fastq files.
o FastqStreamer / FastqSampler warn on incomplete (corrupt) files
CHANGES IN VERSION 1.17
-----------------------

heterogeneous widths, returning a matrix x[i, j] with NA values in
when j > width()[i].
BUG FIXES
o readAligned, type="BAM" correctly adds required 'what' elements
o FastqSampler would only randomize first read; introduced 1.13.9

o report(qa, ...) no longer produces obviously confused base
calls per cycle
o FastqFileList would fail to initialize correctly from a
character vector
CHANGES IN VERSION 1.13
-----------------------
SIGNIFICANT USER-VISIBLE CHANGES

options(srapply_fapply="Rmpi") to enable parallel processing via
fapply
BUG FIXES
o SolexaRealign, SolexaAlign, and SolexaResult transposed strand
information
o FastqSampler segfaulted on some files
o writeFasta had a semi-documented argument mode; it is now
documented and as a consequence dis-allows argument 'append' that
would previously have been passed to underlying methods.
CHANGES IN VERSION 1.9
----------------------
NEW FEATURES
o Support for HiSeq tile layout
o Track reads passing filters, including across logical filter
operations
CHANGES IN VERSION 1.7
----------------------
BUG FIXES
o qa() represented the per-cycle quality scores incorrectly; this
influenced qa[["perCycle"]][["quality"]][["Score"]], but not the
qa report.
o qa() for type="SolexaExport" transposed the 'aligned' and
'filtered' labels on all elements of SolexaExportQA. Thanks
Nicolas Delhomme for the report.
o report() failed when each read was unique. Thanks Peng Yu for
the report.
SIGNIFICANT USER-VISIBLE CHANGES
o The perCycleQuality graph in the qa report now includes boxplots
for all cycles instead of just the median value.
o A depthOfCoverage graph has been added to the qa report for BAM,
Bowtie, SolexaExport and SolexaRealign file types.
o An adapterContamination measure has been added to the qa report for BAM,
Bowtie, SolexaExport, SolexaRealign and Fastq file types.
o srorder is now stable (the original order of identical is
preservered).
NEW FEATURES
o Add class BAMQA. qa() can now be called on BAM files.
o The param argument in readAligned() and qa() for
type="BAM" can now be a single ScanBamParam object
or a list of them.

function ..reduce.
NEW FEATURES
o Optionally retrieve multiplex bar code, paired read number, and
id from SolexaExport (contribution from Nicolas Delhomme)
o renew() and renewable() provide an interface to updating
ShortRead instances
o srapply checks for and uses multicore
o readIntensities supports Illumina RTA '.cif' / '.cnf' files
o readAligned type="BAM" parses BAM files, extracting simple (no
indel) cigars
BUG FIXES
o readIntensities type="IparIntensity" correctly handles multiple
tiles
CHANGES IN VERSION 1.3
----------------------
SIGNIFICANT USER-VISIBLE CHANGES
o coverage,AlignedRead-method has a changed interface (shift/width
rather than start/end) and default behavior (return value in
genome coordinates, rather than minimal covered region).
o readAligned,character-method, type="Bowtie" and readFastq return
FastqQuality by default.
o coverage,AlignedRead-method now returns an RleList
NEW FEATURES
o qa reports from _realign.txt, MAQMap files

o For functions accepting dirPath, pattern to name files, allow
dirPath to be a vector of file names when pattern is character().
o width() on ShortRead and derived classes (including AlignedRead
now returns a vector of widths, of length equal to the length of
the object.
NEW FEATURES

o Add dustyScore() and dustyFilter() to identify low-complexity
regions
o Parse _qseq files (to ShortReadQ or XDataFrame)
o Parse IPAR image intensity files _int.txt.p, _nse.txt.p,
_pos.txt
o Create HTML-based quality assessment reports
o Add trimLRPatterns() for ShortRead and derived classes
(ShortReadQ, AlignedRead).

o readIntensity reads Solexa image intensity files into R,
including information about lane, tile, x, and y coordinates of
each read.
o readPrb returns different types of objects, depending on the
'as' argument of the readPrb,character-method.
o readXStringSet gets arguments skip, nrows; argument order
changed slightly
o New built-in SRFilters positionFilter, uniqueFilter to select
reads aligning to particular positions, or to select only unique
instances of reads aligning to each position.
o readAligned gains a Solexa _results parser (_results files are
listed as 'intermediate' in the Solexa manual, and not a good
end-point for analysis)
o readAligned gains a Bowtie output parser
o readAligned gains ability to parse MAQ 0.7 version binary files
BUG FIXES
o readQual would fail to read 454 quality scores correctly when
these spanned more than one line of input per read
o coverage treated reads as 1 base longer than they were
o FastqQuality got the quality encoding off by one in as(x,
"matrix")
o qa_solexa.Rnw incorrectly displayed read occurences when lanes
were presented out-of-order (an unusual occurence)
o readAligned SolexaAlign, etc., updated to parse 'chromsome' and
'position', and 'strand' information correctly
o readAligned MAQMapview failed for most chromosome labels
CHANGES IN VERSION 1.0
----------------------
SIGNIFICANT USER-VISIBLE CHANGES
o SRFilter allows construction of filters that can be used to
subset existing data objects, or filter incoming (readAligned, at
the moment) objects.
o readAligned for Solexa-based alignments return 'strand'
information as factor with levels "-", "+", "*" (strand not
relevant), NA (no strand information available).
o srorder, srsort, srrank, and srduplicated for AligendRead class
now sort based on chromosome, strand, position AND sread; previous
behavior can be recovers by extracting the sequences
srsort(sread(aln)), etc.
o Functions using SolexaPath now search all relevant directories,
e.g., in analysisPath, rather than the first
BUG FIXES
o 'run' in eland_export files is correctly parsed as a factor
(start date: 29 September, 2008)
