casper (version 2.6.0)

relexprByGene: Compute relative expressions within each gene

Description

Transforms relative expressions that add up to 1 within each gene island (the default output of casper) to relative expressions that add up to 1 per gene.

Usage

relexprByGene(x, normbylength=FALSE, genomeDB)

Arguments

x
ExpressionSet containing relative expressions. (typically, adding up to 1 for each island_id) Column gene_id in fData(x) should contain a unique gene identifier.
normbylength
If set to TRUE, isoform expressions are divided by isoform length before re-normalizing. This is useful for taking into account that longer isoforms produce more reads than shorter isoforms.
genomeDB
If normbylength==TRUE, genomeDB should be an annotatedGenome object containing the annotated genome (see procGenome)

Value

ExpressionSet with relative expressions adding up to one for each gene_id.
