**Dataset formats**

The input dataset is in gd_snp_ format.
The output is a composite dataset, containing both a text table and a PDF plot.
(`Dataset missing?`_)

**What it does**

This tool reports distributions of a SNP reliability indicator, in this case
sequence coverage, for individuals or populations.  
The coverage can be computed for all individuals, a subset of individuals,
or totals for populations defined by the Specify Individuals tool.
The results are reported as a text table giving the cumulative distributions,
and as a plot.
