**Dataset formats**

The input datasets are gd_snp_ and gd_indivs_ formats.
The output dataset is in gd_snp_ format.  (`Dataset missing?`_)

.. _Dataset missing?: ./static/formatHelp.html
.. _gd_snp: ./static/formatHelp.html#gd_snp
.. _gd_indivs: ./static/formatHelp.html#gd_indivs

**What it does**

The user specifies that some of the individuals in the selected gd_snp_ table are
form a "population" that has been previously defined using the Galaxy tool to
select individuals from a gd_snp dataset.  One option is for the program to append
four columns to the table, giving 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), the population's genotype is 2; similarly
for 0; otherwise the genotype is 1 (unless all individuals have undefined
genotype, in which case it is -1.  The other option is to remove rows from
the table for which the total coverage for the population is either too low
or too high, and/or if the individual coverage or quality value is too low.
