Comet parameter: max_variable_mods_in_peptide

• Specifies the total/maximum number of residues that can be modified in a peptide.
• As opposed to specifying the maximum number of variable modifications for each of the 6 possible variable modifications, this entry limits the global number of variable mods possible in each peptide.
• The default value is “5” if this parameter is missing.
• Valid values are “0” (no variable mods) and higher.

Example:

max_variable_mods_in_peptide = 6
max_variable_mods_in_peptide = 10
