◆ OpenMS::FeatureFinderIdentificationAlgorithm::IMStats

struct OpenMS::FeatureFinderIdentificationAlgorithm::IMStats

Ion mobility statistics for a peptide in a specific RT region and charge state.

This structure stores statistical measures of ion mobility values collected from peptide identifications within a single RT region. These statistics are used for:

Chromatogram extraction with appropriate IM windows (using median)
Feature annotation for quality control (all three values)
Detecting potential mis-identifications (large min-max spread may indicate issues)

All values default to -1.0 to indicate missing/unavailable IM data.

Class Members
double	max	Maximum IM value (upper bound of IM distribution)
double	median	Median IM value (robust central tendency, used for extraction)
double	min	Minimum IM value (lower bound of IM distribution)

◆ calculateGlobalIMStats_()

void calculateGlobalIMStats_ ( )

protected

Calculate global IM statistics from MS data and peptide identifications.

Uses MSExperiment::getMinMobility()/getMaxMobility() to get the full IM range from raw data (min/max), and calculates median from peptide identifications for robust central tendency. Must be called BEFORE addSeeds_() to ensure global statistics are based only on identified peptides.

Seeds may or may not have IM annotation depending on the feature finder. Seeds with IM annotation use their own IM value; seeds without IM are extracted across the full IM range of the dataset.

◆ getRTRegionIMStats_()

IMStats getRTRegionIMStats_ ( const RTRegion & r )

protected

Calculate ion mobility statistics for peptide identifications in an RT region.

Computes median, min, and max IM values from peptide identifications within the given RT region (across all charge states). Individual IDs lacking IM annotation are skipped (with warning), and statistics are calculated from the remaining IDs with valid IM data. The median is used for robust central tendency estimation and is more resistant to outliers than the mean.

Seeds from untargeted feature finders may or may not have an IM meta value set, depending on the feature finder. If IM is annotated on the seed, it is used for targeted extraction. If not, the seed is extracted across the full IM range (ChromatogramExtractor disables IM filtering when ion_mobility < 0).

Note: RT region boundaries are determined from ALL IDs (including those without IM), so this only affects IM statistics calculation, not RT extraction.

Parameters

r	RT region containing peptide identifications grouped by charge state

Returns: IMStats structure with median/min/max, or {-1, -1, -1} if no valid IM data

See also: IMStats for details on the returned structure

◆ getRTRegions_()

		FeatureMap &	features,
		const FeatureMap &	seeds = `FeatureMap()`,
		const String &	spectra_file = `""`
	)

Main method for actual FeatureFinder External IDs (peptides_ext, proteins_ext) may be empty, in which case no machine learning or FDR estimation will be performed. Optional seeds from e.g. untargeted FeatureFinders can be added with seeds. Results will be written to features. Note: The primaryMSRunPath of features will be updated to the primaryMSRunPath stored in the MSExperiment. If that path is not a valid and readable mzML spectra_file will be annotated as a fall-back. Caution: peptide IDs will be shrunk to best hit, FFid metavalues added and potential seed IDs added.

FAIMS data is handled automatically: if the MS data contains multiple FAIMS compensation voltages, each CV group is processed independently (with peptide IDs filtered by FAIMS_CV) and results are combined with FAIMS_CV annotation on features. IDs without FAIMS_CV annotation are included in all groups for backward compatibility. For multi-FAIMS data, getLibrary() returns an empty library since each FAIMS group has its own assay library.
