Hello, I want to assemble transcripts from tophat's result, but when I run this command:

stringtie ./tophat_out/accepted_hits.bam -p 16 -G Amborella_trichopoda.AMTR1.0.35.gtf -B -o stout/transcripts.gtf

it reported the error:

GFF Error: overlapping duplicate transcript feature (ID=AMTR_s00001t00279210)

I used a annotation file with GTF format where there isn't a line with "ID=AMTR_s00001t00279210".I don't know what's wrong with it. What should I do? Thank you very much
