**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?`_)

.. _gd_snp: ./static/formatHelp.html#gd_snp
.. _gd_genotype: ./static/formatHelp.html#gd_genotype
.. _gd_indivs: ./static/formatHelp.html#gd_indivs

**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.
