# SYNTHETIC EXAMPLE — this is not anyone's genotype data.
# Generated by DNA Info Lab (https://dnainfolab.org) to illustrate the 23andMe raw-data format.
#
# A real 23andMe export contains roughly 600,000-700,000 rows and begins with a similar block of
# comment lines starting with "#". Positions use genome build GRCh37 (hg19).
# A genotype of "--" means the chip could not read that position (a no-call).
