Function Documentation

encodeTab()

std::string encodeTab

(

const std::string &

to_encode

)

Encodes tabs '\t' in the string as &#x9; and returns the encoded string.

Parameters

[in]

to_encode

The std::string to encode.

Returns

The encoded string.

execAndReset()

bool execAndReset	(	SQLite::Statement &	query,
		int	expected_modifications
	)

Execute and reset an SQL query.

Returns

Whether the number of modifications made by the query matches the expected number

execWithExceptionAndReset()

void execWithExceptionAndReset	(	SQLite::Statement &	query,
		int	expected_modifications,
		int	line,
		const char *	function,
		const char *	context
	)

If execAndReset() returns false, call raiseDBError_()

extractIonImage()

template<typename GetSpectrum >

IonImage extractIonImage	(	const MSImagingGeometry &	geom,
		double	mz,
		double	tolerance_ppm,
		const std::vector< Size > &	pixel_indices,
		Size	n_spectra,
		GetSpectrum &&	get_spectrum
	)

Build an IonImage by summing peak intensities in an m/z window over a pixel subset.

A single extraction kernel shared by MSImagingExperiment and OnDiscImzMLExperiment. The only substantive difference between the two callers is how a spectrum is obtained:

// In-memory (no copy): lambda must declare an explicit return type to avoid
// the silent decay-to-value footgun:
[this](Size i) -> const MSSpectrum& { return experiment_[i]; }
 
// On-disc (value, function-lifetime-extended):
[this](Size i) -> MSSpectrum { return pimpl_->decodeSpectrum(i); }

The const auto& binding inside the loop does the right thing for both cases: it binds the reference directly (no copy, in-memory) or lifetime-extends the temporary for the duration of the loop body (on-disc). A std::function<const MSSpectrum&(Size)> would not work for the on-disc case — it would dangle on the decoded value.

Note

The in-memory lambda must carry an explicit -> const MSSpectrum& return type. An unannotated auto-returning lambda decays to a by-value return and silently reintroduces a copy on the hot in-memory path.

Template Parameters

GetSpectrum

Callable with signature returning MSSpectrum (by value, on-disc) or const MSSpectrum& (by reference, in-memory). The deduced return category determines the binding in const auto& spec.

Parameters

[in]	geom	Imaging pixel grid (dimensions + pixel list).
[in]	mz	m/z center of the extraction window (>= 0).
[in]	tolerance_ppm	Half-window in ppm (>= 0).
[in]	pixel_indices	Indices into geom.getPixels() to process (all pixels or a region subset).
[in]	n_spectra	Total number of spectra in the source (used for bounds checking per pixel).
[in]	get_spectrum	Callable(spectrum_index) -> spectrum.

Returns

Ion image with the same dimensions as geom.

Exceptions

Exception::InvalidValue

if mz or tolerance_ppm is negative or non-finite, or if a pixel references an out-of-range spectrum_index.

fractionGroupAbundances()

FractionGroupAbundanceData fractionGroupAbundances ( const ProteinIdentification::ProteinGroup &  group )

inline

Read PeptideAndProteinQuant's named unit-level arrays and validate their parallel-key contract.

References FractionGroupAbundanceData::error, ProteinIdentification::ProteinGroup::getFloatDataArrays(), ProteinIdentification::ProteinGroup::getIntegerDataArrays(), FractionGroupAbundanceData::present, FractionGroupAbundanceData::valid, and FractionGroupAbundanceData::values.

getOSVersionString_()

std::string getOSVersionString_ ( )

inline

Return the running OS version using a platform-specific probe.

Windows uses RtlGetVersion from ntdll.dll to bypass the compatibility shim and return the real version as "MAJOR.MINOR.BUILD". macOS uses sysctlbyname("kern.osproductversion", ...). Linux (and other __unix__) parses /etc/os-release and returns the VERSION_ID value with surrounding quotes stripped.

Returns "unknown" if the platform query fails or the platform is unsupported.

intensityIteratorWrapper()

template<typename IteratorT >

IntensityIteratorWrapper< IteratorT > intensityIteratorWrapper

(

const IteratorT &

rhs

)

make-function so that we need no write out all those type names to get the wrapped iterator.

operator<<()

template<UInt D>

std::ostream & operator<<	(	std::ostream &	os,
		const DIntervalBase< D > &	rhs
	)

Print the contents to a stream.

References DIntervalBase< D >::maxPosition(), and DIntervalBase< D >::minPosition().

operator==()

bool operator==	(	const IDBoostGraph::ProteinGroup &	lhs,
		const IDBoostGraph::ProteinGroup &	rhs
	)

raiseDBError_()

void raiseDBError_	(	const std::string &	error,
		int	line,
		const char *	function,
		const std::string &	context,
		const std::string &	query = ""
	)

Raise a more informative database error.

Add context to an SQL error encountered by Qt and throw it as a FailedAPICall exception.

Parameters

[in]	error	The error that occurred
[in]	line	Line in the code where error occurred
[in]	function	Name of the function where error occurred
[in]	context	Context for the error
[in]	query	Text of the query that was executed (optional)

Exceptions

Exception::FailedAPICall

Throw this exception

sampleAbundances()

const ProteinIdentification::ProteinGroup::FloatDataArray * sampleAbundances ( const ProteinIdentification::ProteinGroup &  group )

inline

The group's sample-level abundance array, or nullptr when it carries no quantification.

Looked up by NAME rather than by index: PeptideAndProteinQuant names it "abundances" (PeptideAndProteinQuant.cpp) and the positional convention – four float arrays in a fixed order – is an implementation detail of that one writer.

References ProteinIdentification::ProteinGroup::getFloatDataArrays().

validateQuantificationAnnotations()

std::string validateQuantificationAnnotations ( const ProteinIdentification::ProteinGroup::FloatDataArray *  sample_abundances, const FractionGroupAbundanceData &  quantities, Size  design_samples, const QuantificationUnits &  units, const std::set< std::pair< UInt, UInt > > &  expected_quantity_keys  )

inline

Validate one protein group's complete QPX 1.1 quantification annotation contract.

Parameters

[in]	sample_abundances	Optional legacy sample-level abundance array
[in]	quantities	Parsed fraction-group/label abundance arrays
[in]	design_samples	Number of samples in the experimental design
[in]	units	Quantification units derived from the design and ConsensusMap headers
[in]	expected_quantity_keys	Fraction-group/label keys required by units

Returns

An empty string when exportable, otherwise a diagnostic describing the first violation
