Hello!

I am a bit confused with the GTEx version used for the colocalization analyses. Your latest publication mentions v7, so do the data sources.

But as for eQTL data on the Data Portal v8 is being shown, and there was also this announcement [“Genetics Portal v6.0 now live!”](https://community.opentargets.org/t/genetics-portal-v6-0-now-live/408) from November 2021.

So I was wondering which is the GTEx version used for colocalization analysis — specifically when querying for qtlColocalisation data through the API.

Thanks in advance
