Liftoff KeyErrors

Question

[c.eskiw]

Good day all,

Probably a simple fix but I am getting a key error in my Liftoff runs. Not sure how to handle this. Any insight welcome. The command I am using is as follows:

 liftoff target /mnt/f/Genomes/Yeast31_AssembledGenome/contigs.fasta -g /mnt/f/yeastGenomes/Yeast_S288CRefGenome/saccharomyces_cerevisiae.20220727.gff -o /mnt/f/yeastGenomes/Yeast31_AssembledGenome/yeast31.gff3  

The error is as follows:

KeyError: 'chrI'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/ceskiw/miniconda3/bin/liftoff", line 8, in <module>
    sys.exit(main())
  File "/home/ceskiw/miniconda3/lib/python3.9/site-packages/liftoff/run_liftoff.py", line 12, in main
    run_all_liftoff_steps(args)

Cheers! Chris
