chr and pos instead of rsid

[el1717]

Hi all,

I want to run mTAG but most of my SNPs do not have rsIDs. Instead, they have chromosome and position. Can I run mTAG using this information?

Thank you in advance

Hi @el1717 ,

If you're using the builtin/default reference panels in mtag/ld_ref_panel/eur_w_ld_chr/ then unfortunately you have to cross-walk your input files somehow. These reference files use rsID so it's necessary for estimating sigma with ldsc.

Thanks, Hui
