Filters spectra to remove peaks below this signal-to-noise ratio prior to finding features. The noise threshold is determined as described in the manuscript.
Setting this parameter to 1 turns on searches for non-covalently linked dimers (not cross-links). This will no worse than double search time and is only recommended for highly concentrated and purified samples.
