Aggregate Individuals (version 1.1.0)

Dataset formats

The input datasets are in gd_snp, gd_genotype, and gd_indivs formats. The output dataset is in gd_snp or gd_genotype format. (Dataset missing?)


What it does

The user specifies that some of the individuals in a gd_snp or gd_genotype dataset form a "population", by supplying a list that has been previously created using the Specify Individuals tool. The program appends a new "entity" (set of four columns for a gd_snp table, or one column for a gd_genotype table), analogous to the column(s) for an individual but containing summary data for the population as a group. For a gd_snp table, these four columns give the total counts for the two alleles, the "genotype" for the population, and the maximum quality value, taken over all individuals in the population. If all defined genotypes in the population are 2 (agree with the reference), then the population's genotype is 2, and similarly for 0; otherwise the genotype is 1 (unless all individuals have undefined genotype, in which case it is -1). For a gd_genotype file, only the aggregate genotype is appended.
