Major Minor

We allow the major and minor to be determined from either the counts of nucleotides, based on genotype likelihoods or specified by the ancestral/reference.

Inferring Major and Minor alleles

The inference method is chosen based on the data input.

From alignment data

-doMajorMinor 2

-doCount 1

If you input sequencing data like the bam format you can choose to infer the major and minor allele by picking the two most frequently observed bases across individuals. This is the approach from here: citation. To use this appraoch choose

From genotype likelihood data

-doMajorMinor 1

From input for either sequencing data like bam files or from genotype likelihood data like glfv3 the major and minor allele can be inferred directly from likelihoods. We use a maximum likelihood approach to choose the major and minor alleles. Details of the method can be found here and for citation use this publication Skotte2012.

From genotype probability data

-doMajorMinor 3

Currently only genotype probability data in beagle output format is allowed. This format already contains information for the major and minor allele.
