Detailed Description

The LabeledPairFinder allows the matching of labeled features (features with a fixed distance).

Finds feature pairs that have a defined distance in RT and m/z in the same map.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
rt_estimate	string	true	true, false	If 'true' the optimal RT pair distance and deviation are estimated by fitting a gaussian distribution to the histogram of pair distance. Note that this works only datasets with a significant amount of pairs! If 'false' the parameters 'rt_pair_dist', 'rt_dev_low' and 'rt_dev_high' define the optimal distance.
rt_pair_dist	float	-20.0		optimal pair distance in RT [sec] from light to heavy feature
rt_dev_low	float	15.0	min: 0.0	maximum allowed deviation below optimal retention time distance
rt_dev_high	float	15.0	min: 0.0	maximum allowed deviation above optimal retention time distance
mz_pair_dists	float list	[4.0]		optimal pair distances in m/z [Th] for features with charge +1 (adapted to +2, +3, .. by division through charge)
mz_dev	float	0.05	min: 0.0	maximum allowed deviation from optimal m/z distance
mrm	string	false	true, false	this option should be used if the features correspond mrm chromatograms (additionally the precursor is taken into account)

Note:

If a section name is documented, the documentation is displayed as tooltip.
Advanced parameter names are italic.

Todo:

Implement support for labeled MRM experiments, Q1 m/z value and charges. (Andreas)

Implement support for more than one mass delta, e.g. from missed cleavages and so on (Andreas)

◆ run()

void run	(	const std::vector< ConsensusMap > &	input_maps,

Run the algorithm.

Note: Exactly one input map has to be provided.; The output map has to have two file descriptions, containing the same file name. The file descriptions have to be labeled 'heavy' and 'light'.

Exceptions

Exception::IllegalArgument is thrown if the input data is not valid.
