## Comet parameter: database_name

- A full or relative path to the sequence database, in FASTA format, to search. Example databases include RefSeq or UniProt.
- Database can contain amino acid sequences or nucleic acid sequences. If sequences are amino acid sequences, set the parameter "nucleotide_reading_frame = 0". If the sequences are nucleic acid sequences, you must instruct Comet to translate these to amino acid sequences. Do this by setting "nucleotide_reading_frame" to a value between 1 and 9.
- There is no default value if this parameter is missing.

Example:
`database_name = /usr/local/db/yeast.fasta`
`database_name = c:\local\db\yeast.fasta`
`database_name = yeast.fasta`
