Part 1:  Preparing input data

1. Start with a full set of SNP calls from a particular individual, in the masterVar format used by Complete Genomics.
2. Upload the file to a Galaxy history via URL or FTP.
3. Convert to pgSnp format.
4. Obtain a set of SNPs found in healthy individuals from the Galaxy library.
5. Subtract the SNPs found in healthy individuals to narrow the search.
