This is a bash shell script for genotypes outputting through vcf files (which can be downloaded from ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/release/20130502/) based on 1000 Genomes Project using VCFtools.
To run this script, please copy it to the directory that contains the vcf files of 1000 Genomes Project phase 3 data and change directory cd to this directory under bash shell.
Command sh genotype_output.sh would run the script.
Example loci information and population abbreviations shoud be replaced by customized loci information and population abbreviations by editing our script using text editor (e.g. vim, Sublime Text et al.). Other wise, the genotypes of four SNPs (rs2894257, rs9265769, rs7767914, and rs9350317) under chromosome 6 in four populations (GBR, ACB, ASW, and BEB) would be outputted.
