Issue with Extracting Annotations from Custom GFF File

[hj-99]

Dear Author,

Thank you for developing such a practical tool. I am currently encountering an issue while extracting GFF annotations. As you can see in the attached image, an error occurs. The annotation file we are using is based on a self-annotated genome. We suspect that the problem might be related to the GFF format, but we are not entirely sure. Based on your experience, what do you think could be the reason? I look forward to your reply.

Best regards,
