Merge using consensus mode of plink. If genotype is not consistent between datasets it is put to missing.

• sample missing rate 0.1 (removed 3 samples)
  • This is expected due to missing samples on some chips.
• snp missing rate: 0.02 (failed variants 9,244)
• maf 0.001 (failed variants 2)
• 379,885 variants remaining
• 1,268 samples remaining
• Individual genotype callrate: 0.994411
