**Dataset formats**

The input datasets are in gd_snp_, gd_genotype_, and gd_indivs_ formats.
The output dataset is in tabular_ format.

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

**What it does**

The user specifies a SNP table (either gd_snp or gd_genotype format) and
a set of individuals.  The command runs the KING program (Manichaikul et
al., 2010) to look for pairs of distinct individuals in the specified
set that have a close family relationship.  Putatively related pairs
are classified into five categories:

  1. duplicate or MZ twin
  2. 1st degree relatives -- siblings (other than identical twins) or parent-child
  3. 2nd degree relatives -- e.g., half-siblings, grandparent-grandchild pair, individual-uncle/aunt pair
  4. 3rd degree relatives -- e.g., first cousins
  5. unrelated
