Typical biological data coerced into a data frame: a GRanges table representinggenes SSX4 and SSX4B. One row represents one exon, seqnamesindicates the chromosome name, ranges indicates the interval of exons, strandis the direction, tx_id and exon_id are the internal ids used for mappingcross-database.
