Error with GFF input file when using agat_sp_add_introns.pl and agat_convert_sp_gxf2gxf.pl

[mspopecki]

Hello!

I'm trying to add introns to my GFF file using the command agat_sp_add_introns.pl --gff MY.gff --out MY_introns.gff

Unfortunately, I got the below error. I also tried using the commands agat_convert_sp_gff2gtf.pl and agat_convert_sp_gxf2gxf.pl to remake the GFF file in case there were any issues, and also got the same error. How would you recommend proceeding? Thank you!!
