These files describe the exact data used for the paper "Individual
identifiability predicts population identifiability in forensic
genetic markers" by BFB Algee-Hewitt*, MD Edge*, JZ Li, and NA
Rosenberg, Current Biology, 2016. These data are a combination of the
data used for the paper "Clines, clusters, and the effect of study
design on the inference of human population structure" by NA Rosenberg
et al., PLoS Genetics, 2005, and new genotypes from a subset of the
same people considered in the Rosenberg et al study.

1. HGDPmicrosatsIncludingCODIS.stru

This file includes the exact data used by Algee-Hewitt et al.  The
format is that used by the structure program.  The first line gives
the list of loci. The second line indicates whether a locus is a CODIS
locus (codis), a tetranucleotide non-CODIS locus (tetra), or another
kind of locus (other).

After the second line, each person is listed on two
consecutive lines.  The first five columns include the following
information:

(1) Individual code number assigned by HGDP
(2) Population code number assigned by Rosenberg et al. 2002
(3) Population name 
(4) Geographic origin (specific)
(5) Geographic region (Africa, Europe, Middle East, Central/South Asia, 
East Asia, Oceania, or America)

The next columns contain allelic types. The 779 loci with data from
Rosenberg et al. come first. The alleles of these 779 loci are
measured in base pairs.  The final 13 loci are the CODIS loci, all of
which are tetranucleotide repeat loci. 

The CODIS genotypes are measured as follows: if x is the entry in a
data column corresponding to a CODIS locus (columns 793-797), then the
greatest integer less than or equal to x/4 is the number of complete
repeats. The remainder when x is divided by 4 is the number of
additional base pairs. For example, x=49 corresponds to 12 repeats and
1 additional base pair.

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 are denoted by "-9".
