I would like to obtain GWAS Catalog data on hg19 co-ordinates so I use makeCurrentGwascat(genome = "GRCh37"). Everything appears to go smoothly and the object says that it is on hg19 co-ordinates. But if you compare the co-ordinates to what they should be, you will quickly realise that they are still on hg38 co-ordinates despite the liftover appearing to complete successfully. For example, rs56106601 hg38's co-ordinates are chr9:128008205 and its hg19 co-ordinates are chr9:130770484 (https://www.ncbi.nlm.nih.gov/snp/rs56106601), but attempt@elementMetadata[attempt@elementMetadata$SNPS=="rs56106601","CHR_POS"] yields 128008205 - hg38 co-ordinates.
