Humann3/metaphlan 3.0 error md5 checksums do not match

Fantastic thank you this worked. However, I am trying to use humann3 for peptide identification. However, I think my fasta file is parsed incorrectly:

1
LLLARKLKLNLLLLLVLAAK
2
DEARRRMRRWWNARHNHPRRRLWVSRMPR
3
HDMCKWGEWWYQYLPTAYYDCMMAK
4
VKLLKKKKKGAKLLVSVCK

Do you have a required fasta format that is required? I would greatly appreciate knowing what this is!

Best,

Carla
