I have several studies worth of data (In both PLINK and vcf format), and I was wondering if anyone knew of an online tool which I could use to check my chromosome build i.e GRCh37 vs GRCh38. (I thought I used one before but I am since unable to find it).
Or if there are any other suggestions for how to best check this. I guess I could try merging study data with the reference builds and see what aligns best, but this will probably take a while to go through.
Thanks for any help,
