Input

ANSGD currently supports various mapped data, genotype likelihood formats and imputed genotype probability files

genotype probability files

beagle format

Genotype probabilities in beagle format can be used as input. The format used is the haplotype imputation format outputted from beagle [1].

options

To include a beagle file us the option

-beagle [file]

example

The file format is a single linje per site. The first 3 coloums are

• markerName
• alleleA
• alleleB

For each individual 3 coloums are added. These three colums should sum to one.

Example of a file with two individuals

marker alleleA alleleB NA06984 NA06984 NA06984 NA06986 NA06986 NA06986
