ADMIXTOOLS 2 parameters that change your qpAdm results: f2 extraction, allsnps, fudge and friends

The settings tutorials skip and reviewers ask about: extract_f2 versus genotype input, allsnps, maxmiss, fudge and fudge_twice, blgsize, boot, afprod and constrained — what each does, with the measured stakes.

  1. The decision before all others: f2 blocks or genotype input
  2. The numerics: fudge and fudgetwice
  3. The uncertainty machinery: blgsize and boot
  4. The semantics: afprod, constrained, autoonly
  5. The reproducibility block
  6. References
