Detailed Description

data structure for mass shift pattern

Groups of labelled peptides appear with characteristic mass shifts.

For example, for an Arg6 labeled SILAC peptide pair we expect to see mass shifts of 0 and 6 Da. Or as second example, for a peptide pair of a dimethyl labelled sample with a single lysine we will see mass shifts of 56 Da and 64 Da. 28 Da (N-term) + 28 Da (K) and 34 Da (N-term) + 34 Da (K) for light and heavy partners respectively.

The data structure stores the mass shifts and corresponding labels for a group of matching peptide features.

Member Typedef Documentation

◆ LabelSet

typedef std::multiset<String> LabelSet

set of labels associated with a mass shift

For example, a set of SILAC labels [Lys8, Lys8, Arg10] would result in a +26 Da mass shift.
