Bash commands used to filter for final SNP matrix

This file contains the series of bash commands used to filter uneak output to call genotypes using more stringent filters. Starting with the HapMapCount file (for each individual at each tag pair: minimum of 10 tags, heterozygote if the ratio of the two tags < 10, homozygote if the ratio of the two tags > 50, otherwise N), filter the resulting file for sites with alternate homozygous genotypes in the two parent individuals (7,875 sites), filter those sites for a minimum coverage of 50% across all individuals and observed heterozygousity of 0.3–0.7, and then format these genotypes for import into R/qtl.
