Member Function Documentation

◆ getFORMAT() [1/2]

bool vcfpp::BcfRecord::getFORMAT	(	std::string	tag,
		std::vector< std::string > &	v
	)

inline

get tag value in FORMAT

Parameters

tag	valid tag name in FORMAT column declared in the VCF header
v	vector of string

Returns: bool

◆ getFORMAT() [2/2]

template<typename T , typename S = typename T::value_type>

isFormatVector<T> vcfpp::BcfRecord::getFORMAT	(	std::string	tag,
		T &	v
	)

inline

get tag value in FORMAT

Parameters

tag	valid tag name in FORMAT column declared in the VCF header
v	valid input include vector of float, char, int type

Returns: bool

◆ getGenotypes() [1/2]

bool vcfpp::BcfRecord::getGenotypes ( std::vector< int > & v )

inline

fill in the input vector with genotype values, 0, 1 or -9 (missing).

Parameters

v	valid input is vector<int> type

Returns: bool

Note: this function provides full capability to handle all kinds of genotypes in multi-ploidy data costing more spae than the other function. missing allele is set as -9.

◆ getGenotypes() [2/2]

template<typename T >

isValidGT<T> vcfpp::BcfRecord::getGenotypes ( T & v )

inline

fill in the input vector with genotypes of 0 and 1. only works for ploidy<=2. Genotypes with missing allele is coded as heterozygous

Parameters

v	valid input includes vector<bool> and vector<char> type

Returns: bool

Note: use isNoneMissing() to check if all genotypes are with no missingness. Alternatively, one can use vector<int> as the input type as noted in the other overloading function getGenotypes().
