Good day

Thank you for this tool! I'm having trouble with the Phewas option. I have selected a snp on the regional plot, but the phewas option remains grey. What am I doing wrong? image for clarification. Thank you

Thanks for the question. 

I notice your dataset is in build GRCh38, but the "show in context of a pheWAS" option only works for build GRCh37.

The root cause is that the PheWAS we used was published in 2018, and as far as I know, this feature was never updated- hence, it used an older genome build. In practice, the age of the dataset means that you probably won't lose too much by the absence of this feature.

(....actually, there should have been a tooltip explaining the "only for build 37" rule, but it's not appearing for me. That's a tiny cross platform rendering bug...)

Dear Andy

Thanks for getting back to me. Ah I understand, just wanted to make sure I'm not doing something wrong.

Kind regards
Isabel
