Gene position for eqtl analysis

[sumageb]

Hi, I am working on RNA-seq data from wheat. I used stringtie for assembly and followed the IsoformSwitchanalyzeR manual to fix the stringtie issue. My ultimate goal is to do eqtl analysis; for that, I need gene position. I could not find an option from where I can get the gene position along with the id.

I appreciate your help.
