Are you aware of a database or a way to help me in this task: Given a set of ~100 GWAS, how can I collect all the lead and tag SNPs called in these studies and merge them in a big tsv?
What I've done so far was download from EBI GWAS catalog all the GWAS I am interestes in. In this file I have info only on the papers and there is a unique code (e.g.: GCST004599) which redirect to the Open Targets Genetics DB.
I've been trying to recall the variants from the study ID in this DB but no luck so far. They are using a api + graphql structure. The query structure is this. there is no way, to me, to connect StudyID to VariationID.
Did anyone had a similar problem? or can suggest any solutions?
