Detailed Description

generates complete list of all possible mass shifts due to isotopic labelling

Isotopic labelling results in the shift of peptide masses.

For example in a Lys8/Arg10 SILAC labelled sample, some peptides (the ones with one Arg in their sequence) will show a relative mass shift between light and heavy partners of 10 Da. This class constructs the complete list of all possible mass shifts that arise from isotopic labelling.

◆ MultiplexDeltaMassesGenerator() [2/2]

MultiplexDeltaMassesGenerator	(	String	labels,
		int	missed_cleavages,
		std::map< String, double >	label_mass_shift
	)

constructor

Parameters

labels	string describing the labels used in each sample. [...] specifies the labels for a single sample. For example For example, [][Lys8,Arg10] describes a standard SILAC experiment. In the "light" sample, none of the amino acids are labelled []. In the "heavy" sample, lysines and arginines are isotopically labelled [Lys8,Arg10].
missed_cleavages	maximum number of missed cleavages due to incomplete digestion
label_mass_shift	name of labels (e.g. Lys8) and their corresponding mass shifts (e.g. 8.0141988132)

Member Function Documentation

◆ extractLabelSet()

MultiplexDeltaMasses::LabelSet extractLabelSet ( AASequence sequence )

extract the label set from the sequence

Parameters

sequence amino acid sequence

For example, the sequence VLSEEEIDDNFK(Label:13C(6)15N(2))AQR(Label:13C(6)15N(4)) contains a set of two labels, Lys8 and Arg10.

◆ fillLabelMasterList_()

void fillLabelMasterList_ ( )

private

fill label master list

◆ generateKnockoutDeltaMasses()

void generateKnockoutDeltaMasses ( )

generate all mass shifts that can occur due to the absence of one or multiple peptides (e.g. for a triplet experiment generate the doublets and singlets that might be present)

◆ getDeltaMassesList() [1/2]

std::vector<MultiplexDeltaMasses> getDeltaMassesList ( )

returns the list of mass shift patterns

Parameters

stream output stream

◆ getDeltaMassesList() [2/2]

const std::vector<MultiplexDeltaMasses>& getDeltaMassesList ( ) const

Parameters

label short label, as it appears in the "labels" parameter, e.g. "Arg10"

◆ getLabelShort()

String getLabelShort ( String label )

returns the short label string

Parameters

label long label, UniMod name as it appears in peptide sequences, e.g. "Label:13C(6)15N(4)"

◆ getSamplesLabelsList() [1/2]

std::vector<std::vector<String> > getSamplesLabelsList ( )

returns the list of samples with their corresponding labels

For example in a standard SILAC experiment: sample 1: no_label sample 2: Lys8 Arg10

◆ printDeltaMassesList()

void printDeltaMassesList ( std::ostream & stream ) const

For example in a standard SILAC experiment allowing for one missed cleavage, five mass shift patterns are possible. mass shift 1: 0 (no_label) 8.0142 (Lys8) mass shift 2: 0 (no_label) 10.0083 (Arg10) mass shift 3: 0 (no_label) 16.0284 (Lys8,Lys8) mass shift 4: 0 (no_label) 18.0225 (Arg10,Lys8) mass shift 5: 0 (no_label) 20.0165 (Arg10,Arg10)

Parameters

stream output stream

◆ printSamplesLabelsList()

void printSamplesLabelsList ( std::ostream & stream ) const

write the list of labels for each of the sample

For example in a standard SILAC experiment, sample 1 (light) is unlabelled and sample 2 (heavy) contains Lys8 and Arg 10 labels. sample 1: no_label sample 2: Lys8 Arg10
