How to get CHR & POS info on Hg38 using rs Id information?

[Mahantesh-Biradar]

I have a list of SNP rs ids (>1M) for which I would like to find the CHR & POS information. Can you please suggest a suitable tutorial or Jupyter notebook? Thanks in advance

I developed the rsidx package for this purpose, although I've never scaled it up to >1M rsids in a single query. It might need to be broken up into smaller batches, but should still give very good performance.

Thanks, Daniel, let me give it a try.
