Comet parameter: precursor_charge
- This parameter specifies the precursor charge range to search.
- This parameter expects to integer values as input.
- If the first input value is 0 then this parameter is ignored and all charge
states are searched
- If the first input value is not 0 then all charge states between (and inclusive of)
the first and second input values are searched.
Example:
precursor_charge = 0 0 search all charge ranges
precursor_charge = 0 2 search all charge ranges (because first entry is 0)
precursor_charge = 2 6 search 2+ to 6+ precursors
precursor_charge = 3 3 search 3+ precursors
