Simply all I want to know, is there an identifier in ensembl gtfs that indicator which transcript is the 'full-length' transcript. My assumption, is to use the transcript_name provided (i.e. APC-001) where exact transcript in number. I assume the 001 would be the full length transcript, however I need to be sure before I proceed.
If it is not, does anyone have an suggestion how to identify the consensus FL-transcript for the whole transcriptome
