cast_gtf_to_genes(filename, feature = "exon", att_of_interest = "gene_id", ...)

Arguments

filename

path to the gtf file

feature

the feature type name to filter the feature (3rd) column of the gtf/gff file; default is exon

att_of_interest

the attribute to extract from the last column of the gtf/gff file; default in gene_id

...

arguments passed on to other methods

Value

A tibble of the ids, gene names, chromosomes, start and end positions of each exon found in the gtf file.

Examples

fl <- system.file("extdata", "example.gtf.gz", package="Rsamtools", mustWork=TRUE)
cast_gtf_to_genes(fl)
