FastaWriter Class Reference

#include <genesis/sequence/formats/fasta_writer.hpp>

Detailed Description

Write Fasta data.

This class provides simple facilities for writing Fasta data.

Exemplary usage:

std::string outfile = "path/to/file.fasta";
SequenceSet sequence_set;

FastaWriter().line_length( 100 ).write( sequence_set, utils::to_file( outfile ));

See FastaReader for a description of the Fasta format.

Member Function Documentation

abundance_notation() [1/2]

FastaWriter::AbundanceNotation abundance_notation

(

)

const

Get the current setting for how to write abundances.

Definition at line 119 of file fasta_writer.cpp.

abundance_notation() [2/2]

FastaWriter & abundance_notation

(

FastaWriter::AbundanceNotation

value

)

Set the notation for how to write Sequence abundances.

Default is to not write abundances. Use this setting to change that.

Definition at line 113 of file fasta_writer.cpp.

line_length() [1/2]

size_t line_length

(

)

const

Get the current line length.

See the setter line_length( size_t ) for details.

Definition at line 108 of file fasta_writer.cpp.

line_length() [2/2]

FastaWriter & line_length

(

size_t

value

)

Set the line length, which determines after how many chars (Sequence sites) lines breaks are inserted when writing the Fasta file.

Default is 80. If set to 0, no breaks are inserted. The functions returns the FastaWriter object to allow fluent interfaces.

write() [1/2]

void write	(	Sequence const &	sequence,
		std::shared_ptr< utils::BaseOutputTarget >	target
	)		const

Write a single Sequence to an output target, using the Fasta format.

See the output target convenience functions utils::to_file(), utils::to_stream(), and utils::to_string() for examples of how to obtain a suitable output target.

Definition at line 50 of file fasta_writer.cpp.

write() [2/2]

void write	(	SequenceSet const &	sequence_set,
		std::shared_ptr< utils::BaseOutputTarget >	target
	)		const

Write a SequenceSet to an output target, using the Fasta format.

See the output target convenience functions utils::to_file(), utils::to_stream(), and utils::to_string() for examples of how to obtain a suitable output target.

Definition at line 55 of file fasta_writer.cpp.

write_sequence()

void write_sequence	(	Sequence const &	sequence,
		std::ostream &	os
	)		const

Write a single Sequence to an output stream in Fasta format.

Definition at line 63 of file fasta_writer.cpp.

Member Enumeration Documentation

AbundanceNotation

enum AbundanceNotation

strong

Enumeration of types for how to write Sequence abundances.

Enumerator
kNone	Do not write abundances. This is the default.
kUnderscore	Write abundances appaneded by an underscore: abc_123.
kSize	Write abundances appended as a text of the form abc;size=123
