Detailed Description

FeatureFinderAlgorithm for MRM experiments.

Experimental classes:
This tool has not been tested thoroughly and might behave not as expected!

This very simple algorithm has mainly been tested on data generated on an ABI/SCIEX QTrap 4000. Maybe this algorithm cannot be directly applied on data generated by other mass spectrometers.

Precursor m/z information (Q1) is stored in the "MZ" metavalue of each feature! The feature's m/z itself is the Q3's ion m/z.

Parameters of this class are:

NameTypeDefaultRestrictionsDescription
min_rt_distance float10.0 min: 0.0Minimal distance of MRM features in seconds.
min_num_peaks_per_feature int5 min: 1Minimal number of peaks which are needed for a single feature
min_signal_to_noise_ratio float2.0 min: 0.0Minimal S/N ratio a peak must have to be taken into account. Set to zero if the MRM-traces contains mostly signals, and no noise.
write_debug_files stringfalse true, falseIf set to true, for each feature a plot will be created, in the subdirectory 'debug'
resample_traces stringfalse true, falseIf set to true, each trace, which is in this case a part of the MRM monitoring trace with signal is resampled, using the minimal distance of two data points in RT dimension
write_debuginfo stringfalse true, falseIf set to true, debug messages are written, the output can be somewhat lengthy.

Main method for actual FeatureFinder.

Implements FeatureFinderAlgorithm.

This method is used to update extra member variables at the end of the setParameters() method.

Also call it at the end of the derived classes' copy constructor and assignment operator.

The default implementation is empty.

Reimplemented from DefaultParamHandler.
