In MRCIEU/MRInstruments: Data sources for genetic instruments to be used in MR

Downloaded from EBI on 18/03/2016. Standardised to make units as consistent as possible, trait names, obtain gene annotation. Effect sizes and standard errors are all converted to log odds ratio for binary traits. Ensembl used to identify alleles and effect allele frequency where missing.
