Member Function Documentation

constructTargetDecoyMassMapping()

static std::vector<MetaboTargetDecoyMassMapping> constructTargetDecoyMassMapping ( const TargetedExperiment &  t_exp )

static

Constructs a mass mapping of targets and decoys using a the unique mids identifier.

Parameters

t_exp

TransitionExperiment holds compound and transition information used for the mapping.

generateMissingDecoysByMassShift()

static void generateMissingDecoysByMassShift ( TargetedExperiment &  t_exp, std::vector< MetaboTargetedTargetDecoy::MetaboTargetDecoyMassMapping > &  mappings, const double &  mass_to_add  )

static

Generate a decoy for targets where fragmentation tree re-rooting was not possible, by adding a specifiable mass to the target fragments.

Parameters

t_exp	TransitionExperiment holds compound and transition information
mappings	map of identifier to target and decoy masses
mass_to_add	the maximum number of transitions required per assay

resolveOverlappingTargetDecoyMassesByIndividualMassShift()

static void resolveOverlappingTargetDecoyMassesByIndividualMassShift ( TargetedExperiment &  t_exp, std::vector< MetaboTargetedTargetDecoy::MetaboTargetDecoyMassMapping > &  mappings, const double &  mass_to_add  )

static

Resolves overlapping target and decoy transitions masses by adding a specifiable mass to the overlapping decoy fragment.

Parameters

t_exp	TransitionExperiment holds compound and transition information
mappings	map of identifier to target and decoy masses
mass_to_add
