Comet parameter: fragindex_min_fragmentmass

• This parameter defines the minimum fragment ion mass to include in the fragment ion index.
• The mass is the singly charged fragment mass.
• A larger value will use less memory and generate the fragment ion index faster as less fragment ions will be added to the index.
• Specifying too large a value may remove fragment ions from consideration that would otherwise aid in peptides passing the fragment ion index filter.
• If this value is not specified, the default value is 200.0.
• Valid values are a positive decimal number.

Example:

fragindex_min_fragmentmass = 200.0
