Sample exon data GRanges

Description

Sample exon data GRanges

Usage

test_exon_gr

Format

GRanges object where each segment represents one exon for an arbitrary gene. It has one column of values, "gene_name" used for Sashimi plot preparation.

Details

This dataset contains RNA-seq splice junction data stored as a GRangesList.
