More Research on GWAS and GS By May 31, 2013
As fast as one season 50~300 kb resolution
Problems in GWAS 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
