 6. Filter novel transcripts based on [bambu NDR (Novel Discovery Rates)](https://github.com/GoekeLab/bambu) and/or [TransforKmers TSS validation](https://github.com/IGDRion/transforkmers) to assess fulllength transcripts.
 7. Perform a quality control of both the full and filtered extended annotations (see [example](https://github.com/igdrion/ANNEXA/blob/master/examples/results/qc_gtf.pdf)).
 8. Optional: Check gene body coverage with [RSeQC](http://rseqc.sourceforge.net/#genebody-coverage-py).
