Variant Struct Reference

#include <genesis/population/variant.hpp>

Detailed Description

A single variant at a position in a chromosome, along with BaseCounts for a set of samples.

Typically, this class is used as a general representation of the variants/SNPs at a given chromosome position, for example coming from a line in a VCF file or (m)pileup file.

The class consists of the following data fields:

  • A chromosome and position.
  • The reference base and alternative base at that position (which might not always be available in the input file format, in which case we use 'N'). Note that we currently only support one alternative base here, that is, biallelic variants only.
  • A set of BaseCountss, that is, information on the counts of nucleotide bases of thereads of a set of pool samples or individuals that cover this variants/SNPs at that position. See BaseCounts for details on the latter.
