Detailed Description

The clustal sequence file format.

An AlignedSequenceContainer object is used instead of a VectorSequenceContainer.

bpp::Clustal::Clustal	(	bool	checkSequenceNames = `true`,
		unsigned int	nbExtraSpacesBeforeSeq = `5`,
		unsigned int	charsByLine = `100`
	)		throw (Exception)

inline

Build a new Clustal object.

Parameters

checkSequenceNames	Tell if the names in the file should be checked for unicity (slower, in o(n*n) where n is the number of sequences).
nbExtraSpacesBeforeSeq	Specify the number of extra space characters separating the sequence name form content. The default is 5 (hence 6 spaces in total) for backward compatibility, using 0 will not allow for any space in the sequence names.
charsByLine	Number of character per line when writing file.
