**Dataset formats**

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

**What it does**

This tool converts a gd_snp dataset into the format needed for estimating
the population structure.  You can select the individuals to be included,
by using "population" datasets created via the Specify Individuals tool.
(It is important for these population datasets to have distinguishable names,
since they will be stored in the output's metadata so that subsequent tools
can use them as labels.  If necessary, rename the datasets to give them
distinct and meaningful names before running this tool.)

You can also filter the SNPs, based on criteria such as minimum coverage
(a qualifying SNP must have at least this many reads for every included
individual), minimum quality score (for every included individual), and/or
minimum spacing (SNPs that are too close together on the same chromosome or
scaffold are discarded).  In addition to producing the filtered and formatted
.map and .ped files for subsequent analysis, the tool reports the number of
SNPs meeting these conditions, which can be seen by clicking on the eye icon
in the history panel after the program runs.
