REF3UTR {APAlyzer} | R Documentation

## REF3UTR, build reference regions for 3'UTR PASs

### Description

Build 3'UTR PAS Reference for distal and proximal PAS.

### Usage

        REF3UTR(refUTR)

### Arguments

`refUTR` | a dataframe containing 6 colmuns for 3'UTR PASs: 'gene_symbol', 'Chrom', 'Strand', 'Proximal', 'Distal', 'cdsend'

### Value

The function `REF3UTR()` returns a genomic ranges of aUTR(pPAS to dPAS) and cUTR(cdsend to pPAS) regions for each gene

### Author(s)

### Examples

    ## build Reference ranges for 3'UTR PASs in human
        extpath = system.file("extdata", "mm9_REF.RData", package="APAlyzer")
        load(extpath)
        refUTRraw=refUTRraw[which(refUTRraw$Chrom=='chr19'),]
        UTRdbraw=REF3UTR(refUTRraw)
