Mechanism of handling modifications. (A) For a crosslinked peptide with three modifiable sites M1, M2, and M3, with 2, 1, and 1 possible types of modifications at each site, respectively, CLPM will generate its derivatives. (B) Masses are calculated for each possible combination of derivatives. BM represents the basic mass minus the mass of a peptide without adding any modifications.
