minPWMScore {ChIPanalyser} | R Documentation

## Accessor method the `minPWMScore` slot in a `genomicProfileParameters` object

### Description

Accessor method the `minPWMScore` slot in a `genomicProfileParameters` object

### Usage

    minPWMScore(object)

### Arguments

`object` | `object` is a `genomicProfileParameters` object.

### Details

`minPWMScore` can be described as the lowest PWM score computed at a genome wide scale. Although it is possible to assigne a value to `minPWMScore`, we strongly advise to use the value computed and assigned internally. This value is computed in the `computeGenomeWidePWMScore` function.

### Value

Returns the value assigned to the `minPWMScore` slot in a `genomicProfileParameters` object.

### Examples

    #Data extraction
    data(ChIPanalyserData)
    # path to Position Frequency Matrix
    PFM <- file.path(system.file("extdata",package="ChIPanalyser"),"BCDSlx.pfm")
    #As an example of genome, this example will run on the Drosophila genome

    if(!require("BSgenome.Dmelanogaster.UCSC.dm3", character.only = TRUE)){
        source("https://bioconductor.org/biocLite.R")
        biocLite("BSgenome.Dmelanogaster.UCSC.dm3")
    }
    library(BSgenome.Dmelanogaster.UCSC.dm3)
    DNASequenceSet <- getSeq(BSgenome.Dmelanogaster.UCSC.dm3)
    #Building data objects
    GPP <- genomicProfileParameters(PFM=PFM)

    # Computing Genome Wide
    GenomceWide <- computeGenomeWidePWMScore(DNASequenceSet = DNASequenceSet,
        genomicProfileParameters = GPP)
    minPWMScore(GenomceWide)

    ## If used before computeGenomeWidePWMScore, will return NULL
