I have obtained a list of ~1000 SNPs from GWAS catalog, i.e:
For which I need the genomic position.
The GWAS catalog website states:
"The SNP data in the catalog has been mapped to dbSNP Build 141 and Genome Assembly, GRCh38/hg38."
However, dbSNP build 141 should be mapped to both hg19 and hg38.
What's an easy way to retrieve the hg19 position of the SNPs in question? Preferably using R or a web GUI.
