PEPPAN fails with UnboundLocalError using PGAP-annotated gff/fna files

[MrTomRod]

Describe the bug
PEPPAN fails with "UnboundLocalError: local variable 'name' referenced before assignment"

To Reproduce

1. Install PEPPAN

# install via conda
conda config --add channels defaults
conda config --add channels conda-forge
conda config --add channels bioconda
conda create --prefix ./conda-envs/peppan python=3.9
conda activate /data/users/username/conda-envs/peppan
conda install mmseqs2 blast diamond rapidnj fasttree
pip3 install peppan

# quickstart
PEPPAN --testunit
PEPPAN -p examples/ST131 -P examples/GCF_000010485.combined.gff.gz examples/*.gff.gz > 1_PEPPAN.out 2>&1
PEPPAN_parser -g examples/ST131.PEPPAN.gff -s examples/PEPPAN_out -t -c -a 95 > 2_PEPPAN_parser.out 2>&1

2. Download data

• FAM14217: gff, fna
• FAM15300: gff, fna

3. Run PEPPAN

$ conda activate /data/users/username/conda-envs/peppan
$ cd /data/users/username/genome_datasets
$ PEPPAN \
> --prefix PEPPAN_50/my-prefix \
> --genes \
> in/FAM14217-p1-1.1.gff,in/FAM14217-p1-1.1.fna \
> in/FAM15300-i1-1.1.gff,in/FAM15300-i1-1.1.fna
