markDuplicates: Program dispatchers to mark duplicated reads from a BAM file

In dupRadar: Assessment of duplication rates in RNA-Seq datasets

Description

markDuplicates Mark duplicated reads from a BAM file by calling widely used tools.

Usage

markDuplicates(dupremover = "bamutil", bam = NULL, out = gsub("\\.bam$",
  "_duprm.bam", bam), rminput = TRUE, path = ".", verbose = TRUE, ...)

Arguments

dupremover	The tool to be called. Currently, "picard" and "bamutils" are supported
bam	The bam file to mark duplicates from
out	Regular expression describing the transformation on the original filename to get the output filename. By default, a "_duprm" suffix is added before the bam extension
rminput	Whether to keep the original, non duplicate-marked, bam file
path	Path to the duplicate marker binaries
verbose	Redirect all the program output to the R console
...	Other parameters sent to the caller function

Details

This function works as a wrapper for several tools widely adopted tr mark duplicated reads in a BAM file. Currently, it supports PICARD and BamUtils.

Value

The output filename

Examples

## Not run: 
bam <- system.file("extdata","sample1Aligned.out.bam",package="dupRadar")
gtf <- "genes.gtf"
stranded <- 2    # '0' (unstranded), '1' (stranded) and '2' (reverse)
paired   <- FALSE
threads  <- 4

# call the duplicate marker and analyze the reads
bamDuprm <- markDuplicates(dupremover="bamutil",bam,
                           path="/opt/bamUtil-master/bin",rminput=FALSE)
dm <- analyzeDuprates(bamDuprm,gtf,stranded,paired,threads)

## End(Not run)
