Limitations of vtools genotype database #11

Closed gaow closed 7 years ago

gaow commented 7 years ago
  1. It is not sparse for simple scenarios (where genotypes are coded 0/1/2/NA)
  2. It does not distinguish between 0 and NA, unless we specifically asks it
  3. It does not store phase information
  4. It only accepts integers, not imputed genotypes
  5. Storing various annotations makes the genotype database painfully complex
