Detailed Description

This class serves for reading in and writing OpenSWATH OSW files.

See OpenSwathOSWWriter for more functionality.

The reader and writer returns data in a format suitable for PercolatorAdapter. OSW files have a flexible data structure. They contain all peptide query parameters of TraML/PQP files with the detected and quantified features of OpenSwathWorkflow (feature, feature_ms1, feature_ms2 & feature_transition).

The OSWFile reader extracts the feature information from the OSW file for each level (MS1, MS2 & transition) separately and generates Percolator input files. For each of the three Percolator reports, OSWFile writer adds a table (score_ms1, score_ms2, score_transition) with the respective confidence metrics. These tables can be mapped to the corresponding feature tables, are very similar to PyProphet results and can thus be used interchangeably.

Constructor & Destructor Documentation

◆ OSWFile() [1/2]

OSWFile ( const String filename)

opens an OSW file for reading.

Exceptions
Exception::FileNotReadableif filename does not exist

◆ OSWFile() [2/2]

OSWFile ( const OSWFile rhs)
default

Member Function Documentation

◆ getFullProteins_()

void getFullProteins_ ( OSWData swath_result,
Size  prot_index = ALL_PROTEINS 
)
protected

fill one (prot_id) or all proteins into swath_result

Parameters
[out]swath_resultOutput data. Proteins are cleared before if ALL_PROTEINS is used.
prot_indexUsing ALL_PROTEINS queries all proteins (could take some time)

◆ getRunID()

UInt64 getRunID ( ) const

extract the RUN::ID from the sqMass file

Exceptions
Exception::SqlOperationFailedmore than on run exists

◆ operator=()

OSWFile& operator= ( const OSWFile rhs)
default

◆ read()

void read ( OSWData swath_result)

read data from an SQLLite OSW file into swath_result Depending on the number of proteins, this could take a while.

Note
If you just want the proteins and transitions without peptides and features, use readMinimal().

◆ readMeta_()

void readMeta_ ( OSWData data)
protected

set source file and sqMass run-ID

◆ readMinimal()

void readMinimal ( OSWData swath_result)

Reads in transitions and a list of protein names/IDs but no peptide/feature/transition mapping data (which could be very expensive). Use in conjunction with on-demand readProtein() to fully populate proteins with peptide/feature data as needed.

Note
If you read in all proteins afterwards in one go anyway, using the read() method will be faster (by about 30%)

◆ readProtein()

void readProtein ( OSWData swath_result,
const Size  index 
)

populates a protein at index index within swath_results with Peptides, unless the protein already has peptides

Internally uses the proteins ID to search for cross referencing peptides and transitions in the OSW file.

Parameters
swath_resultOSWData obtained from the readMinimal() method
indexIndex into swath_result.getProteins()[index]. Make sure the index is within the vector's size.
Exceptions
Exception::InvalidValueif the protein at index does not have any peptides present in the OSW file

◆ readToPIN()

static void readToPIN ( const std::string &  filename,
const OSWFile::OSWLevel  osw_level,
std::ostream &  pin_output,
const double  ipf_max_peakgroup_pep,
const double  ipf_max_transition_isotope_overlap,
const double  ipf_min_transition_sn 
)
static

Reads an OSW SQLite file and returns the data on MS1-, MS2- or transition-level as ostream (e.g. stringstream or ofstream).

◆ readTransitions_()

void readTransitions_ ( OSWData swath_result)
protected

populate transitions of swath_result

Clears swath_result entirely (incl. proteins) before adding transitions.

◆ writeFromPercolator()

static void writeFromPercolator ( const std::string &  osw_filename,
const OSWFile::OSWLevel  osw_level,
const std::map< std::string, PercolatorFeature > &  features 
)
static

Updates an OpenSWATH OSW SQLite file with the MS1-, MS2- or transition-level results of Percolator.
