The S4 class representing a collection of information about the reference build

Description

Objects of this class are a collection of references derived from a list of parameters.

Usage

EzRef(param)

## S4 method for signature 'EzRef,ANY'
x[i]

## S4 replacement method for signature 'EzRef,ANY,ANY,ANY'
x[i] <- value

Methods (by generic)

• x[i: Access of slots by name with square brackets [ ]

• `[`(x = EzRef, i = ANY, j = ANY) <- value: Assignment to slots by name with square brackets [ ]

Functions

• EzRef(): Initializes the slots of EzRef. It will also try to specify some fields and if necessary get full file paths.

Slots

refBuild

a character specifying the file path to the reference build.

refBuildName

a character specifying the name of the reference build.

refBuildDir

a character specifying the directory of the reference build.

refIndex

a character specifying the location of the index that is used in the alignment.

refFeatureFile

a character specifying the file path to the annotation feature file (.gtf).

refAnnotationFile

a character specifying the file path to the annotation file (.txt). Subsetting species are automatically removed

refFastaFile

a character specifying the file path to the fasta file.

refChromSizesFile

a character specifying the file path to the file containing the chromosome sizes.

refAnnotationVersion

a character specifying the annotation version.
