This file describes the exact data used in the Pemberton et al (2009)
BMC Genomics article "Sequence determinants of human microsatellite variability."

The 627 loci in the new data are a subset of the 783 microsatellite 
loci in the Ramachandran et al. (2005) PNAS article "Support from the 
relationship of genetic and geographic distance in human populations 
for a serial founder effect originating in Africa" and in the Rosenberg
et al. (2005) PLoS Genetics article "Clines, clusters, and the effect
of study design on the inference of human population structure."

The new data set contains genotypes in the form of the number of repeats
they represent rather than the PCR fragment sizes used in Ramachandran et al.
(2005) and Rosenberg et al. (2005).  For a description of how PCR fragment
sizes were converted into number of repeats and how these loci were selected
please see Pemberton et al. (2009).

1. combinedmicrosats_627loci_1048indivs_numRpts.stru

This file includes the exact data used by Pemberton et al. (2009).
The format is that used by the structure program. The first line 
gives the list of microsatellites. The second line gives the size 
of microsatellite repeat units in nucleotides (2 = di, 3 = tri,
4 = tetra). The third line gives the number of separate short tandem 
repeat (STR) regions in microsatellite sequences (1, 2, or 3). 
The fourth line states whether the alleles in the HGDP-CEPH individuals 
are regular (all alleles are separated by exact multiples of the 
repeat unit size) or irregular (one or more alleles are not 
separated by exact multiples of the repeat unit size). After the 
first four lines, each individual is listed on two consecutive 
lines. The first five columns include the following information:

(1) Individual code number assigned by CEPH.
(2) Population code number, as was used in Rosenberg et al. (2002).
(3) Population name.
(4) Geographic information about the population.
(5) Pre-defined region, as was used in Rosenberg et al. (2002).
