Detailed Description

Export protein group data to Apache Arrow format following QPX pg schema.

This class provides static methods to export protein group quantification data from a ConsensusMap to Apache Arrow Tables and Parquet files. The schema follows the QPX (Quantitative Proteomics Exchange) protein group format.

Protein groups must have quantification annotated via PeptideAndProteinQuant::annotateQuantificationsToProteins() before export.

Experimental classes:: This API is experimental and may change in future versions.

◆ exportToArrow()

static std::shared_ptr< arrow::Table > exportToArrow ( const ConsensusMap & cmap )

static

Export protein group data to Apache Arrow Table.

Exports indistinguishable protein groups following the QPX pg schema. One row is emitted per protein group per run file.

Parameters

[in] cmap The ConsensusMap with annotated protein group quantification

Returns: Shared pointer to Arrow Table, or nullptr on error

◆ exportToParquet()

static bool exportToParquet	(	const ConsensusMap &	cmap,
		const String &	filename,
		const ParquetWriteConfig &	config = `ParquetWriteConfig{}`
	)
