In fischuu/GenomicTools: Collection of Tools for Genomic Data Analysis

Extract the Chromosomal Information Required in bed Format from an imported gtf table.

Description

This function creates a matrix of gene annotations in bed format, based on the information given in an importet gtf table.

Usage

  gtfToBed(gtf, correctBases=TRUE)

Arguments

gtf	An imported gtf table.
correctBases	Logical subtract 1 from bases

Details

After a gtf file was imported with importGTF this function transforms it into a data.frame with bed formatting. The option correctBases adjusts the coordinates in the bed object according to the bed standard. The base counting in gtf starts with 1, wheras in bed-files they start with 0.

Value

A data.frame in bed format having the four columns Chr, Start, Stop and Gene
