duplicateRate-methods: Retrieve duplication rates

In ChIPQC: Quality metrics for ChIPseq data

Description

Retrieve duplication rates.

Methods

signature(object = "ChIPQCexperiment", bFiltered)

Retrieve a vector of the duplication rates for each sample in an experiment. A read is considered duplicated if another read maps to the same genomic location; the duplication rate is the number of duplicated reads divided by the total number of reads for a sample. If bFiltered=TRUE (or is missing), only reads that pass the mapping quality filter for each sample are included. if bFiltered=FALSE, all reads for each sample will be included.

signature(object = "list", bFiltered)

Retrieve a vector of the duplication rates for each sample in a list of ChIPQCsample objects. A read is considered duplicated if another read maps to the same genomic location; the duplication rate is the number of duplicated reads divided by the total number of reads for a sample. If bFiltered=TRUE (or is missing), only reads that pass the mapping quality filter for each sample are included. if bFiltered=FALSE, all reads for each sample will be included.
