gtf issue with talon_initialize_database

[dl870]

Hi, I am having an issue with talon_initialize_database after reformatting my gtf - sr_reformatted.txt
I get the following error when running : talon_initialize_database --f sr_reformatted.gft --a Sr18 --g WsBPS18 --o sr_flf1

bulk update genes...
bulk update gene_annotations...
Traceback (most recent call last):

KeyError: 'None'

I don't know if its the GTF file error or not? I tried running it without reformatting and it ran but then talon couldn't find the annotations later.

Cheers!
