[Bioperl-l] How to use module Bio::SeqFeature::Gene::GeneStructure?

[Tao Zhu]

I've referred the ducument
http://doc.bioperl.org/releases/bioperl-current/bioperl-live/Bio/SeqFeature/Gene/GeneStructure.html
It says, @transcripts = $gene->transcripts(); @exons = $gene->exons();
The object $gene should mean a Bio::SeqFeature::Gene::GeneStructure
object. But how could I get such object? I hope to see a good example.
Thank you!
