### Details

The SetID file is a white-space (space or tab) delimitered file with 2 columns: SetID and SNP_ID.

Please keep in mind that there should be no header! The SNP_IDs and SetIDs should be less than 50 characters, otherwise, it will return an error message.

The SSD file is a binary formated file with genotypes. The SSD info file is a text file with general information on data and SNP sets (first 6 rows), and information on each set (after 8th row).
