 As fast as one season  50~300 kb resolution

 Computing difficulties: millions of markers, individuals, and traits  False positives, ex: “Amgen scientists tried to replicate 53 high-profile cancer research findings, but could only replicate 6”, Nature, 2012, 483: 531  False negatives Problems in GWAS
