file

The path to a FASTA file containing sequences to use. Either "input" or "file" must be supplied but not both.

A character vector of sequences

See the example below for what this looks like. The parser read_fasta produces output like this.

A list of character vectors

Each vector should have one base per element.

A "DNAbin" object

This is the result of parsers like read.FASTA.
