  1. − 10lgP = Conversion form of P-value in PEAKS 8.5 software where P-value of 1% is equivalent to − 10lgP of 20
  2. ppm delta Mass is the deviation of measured mass from the theoretical mass of the peptide, in ppm, m/z mass of ions (in gas phase) per charge, RT relatively accurate prediction of peptide, PTM post translational modification, NQ variable modification deamidation NQ (+ 0.98 Da) of asparagines (N) and glutamines (Q)
