  1. aFor each tick, four technical replicate mass spectra were matched against designed SSp. and a final ID assigned accordingly
  2. CC: one correct SSp. matching; C: multiple SSp. matching, correct SSp. as top match; N: no matching SSp
  3. other: true ID was assigned based on a different combination
