WebNov 7, 2013 · The focus of this research is peak selection. The objective of this step is to identify informative peaks in the spectrum. We are particulary interested in peaks that represent b-/y-ions. An ideal MS/MS spectrum would be free of noise and contain all of the prefix (N-terminal b-ion) and suffix (C-terminal y-ion) fragments. In practice, the MS ...
