Hello !
I have a question about an interpretation done by stringtie, using Nanopore datas. I generated my bam files with minimap2 and used them as input of stringtie without a guided file with the followed command :
minimap2
stringtie \ -L \ -o <my output file> <my bam file>
On one sample we should observe an exon duplication. On IGV we see this duplication :
And with the following coordinated :
However using stringtie, duplication is consider as an insertion and merged with the exon annotated as 7 :

Is it a normal behavior ? Because I would expect as transcript annotation a duplication of coordinates around exon 7.
Thanks for your help !
