[BioC] Create transcriptDb using gff3 files? - library GenomicFeatures and rtracklayer

[Sang Chul Choi]

Hi,

I am wondering if I could create a TranscriptDb object (library GenomicFeatures) using a gff3 file.  I could read a gff3 file using import.gff3, but I could not find a way to create TranscriptDb object from the object from import.gff3.

Two arguments for makeTranscriptDb are required: transcripts, splicings. It does not seem to be easy to parse this information from the object form import.gff3.  I will appreciate any help.

Thank you,
