Comet parameter: decoy_prefix

• This parameter specifies the prefix string that is pre-pended to the protein identifier and reported for decoy hits.
• This parameter is only valid when a decoy_search is performed.
• For example, if the prefix parameter is set to “decoy_prefix = reverse_”, a match to a decoy peptide from protein “ALBU_HUMAN” would return “reverse_ALBU_HUMAN” as the protein identifier.
• The default value is “DECOY_” if this parameter is missing.

Example:

decoy_prefix = DECOY_
decoy_prefix = rev_
decoy_prefix = --any_string_you_want_without_spaces--
