- Naive tryptic digestion (split after every K,R - consider c-terminal P)
- Proteolytic incomplete digestion - with a certain percentage, not every fragment is digested at K or R
(- Tryptic digestion of K,R and only modified C's) missing references for digestion of C, hence it was excluded
(implemented)
(2) Post-translational modifications
- Some modifications taken from unimod.org were used for post-translational modifications
(implemented)
(3) Comparison of feature mass and quality values with theoretical mass and their distance
