Filtering at the Table Browser

Remember these disease SNPs can be found in healthy carriers in the population. So we can not be sure that any SNPs only found as heterozygous are not the disease SNPs. We will filter and import only the homozygous SNPs for subtracting from our pedigree results. Also because of looking for homozygous SNPs we want only fully sequenced genomes to increase the likelyhood of the homozygous call being correct. In a low coverage genome it is difficult to tell a homozygous SNP from an heterozygous one where by chance only one allele was found.

The filter here is similar to what we did in Galaxy, we want the alleleCount column to be equal to one (red arrows). Then click the submit button (green arrow).
