The file hgdpamer_1484_678.stru provides the data used in the article
"Genetic variation and population structure in Native Americans".

This file includes the genotypes for 1484 individuals at 678 loci.
The individuals include 1048 individuals from the HGDP-CEPH diversity
panel and 436 individuals newly genotyped for the article.

As described in the article, genotypes of the new 436 individuals have
been aligned in this file to match the allele sizes in previous data
sets from the HGDP.

The format of the file is that used by the Structure program.  The
first line gives the list of loci. After the first line, each
individual is listed on two consecutive lines.  The first five columns
include the following information:

(1) Individual code number --- for HGDP-CEPH individuals, these code
    numbers match the numbers previously used.
(2) Population code number assigned by us.
(3) Population name.
(4) Geographic information about the population.
(5) Geographic region.

The next columns contain genotypes (measured in base pairs). The 
left-to-right order of the genotypes corresponds to the
left-to-right order of the locus names on the first line of the file. 
The placement of genotypes on the first versus second line for an
individual is arbitrary.  Missing data is denoted by "-9".
