Error: gene_biotype = re.search(r'(gene_type|gene_biotype|transcript_biotype|transcript_type) "(.*?)";', ids).group(2) AttributeError: 'NoneType' object has no attribute 'group'
Release date : Jan 27,2026
- Versions 1.2.1 and earlier require the GTF file's attribute column to record the gene's biotype.
- If this error occurs, either modify the GTF file to include gene biotypes or use version 1.2.2 or later, where the biotype defaults to "undefine".
