I encounter a problem in multimer prediction with the sequences I use as input.

It's always indicating:

"Missing or invalid "sequences" argument: Sequences argument"

and " is not a chain specifier, alignment id, UniProt id, or sequence characters"

The input format is always something like a fasta format:

>seq_id

ACCCC

>seq_id2

ALLPAAAA

May I know how I can rectify this?

Thanks!
