Hi everyone,

I was wondering if there is a way to query an older version of the Open Targets Platform (specifically version 24.09). I only need the number of targets associated with “neurodegenerative disease” (EFO = EFO\_0005772) in that specific release.

Alternatively, if someone already has that data and could share it, I’d be very grateful!

Many thanks,  
Vittorio

Hi Vittorio!

We had _8,613_ targets somehow related to neurodegenerative disease. This number goes up to _13,408_ if you consider associations from all child terms.

All data from our previous releases is available on the [FTP](https://ftp.ebi.ac.uk/pub/databases/opentargets/platform/24.09/) and in the ``gs://open-targets-data-releases``bucket on Google Cloud. The datasets you should be querying are `associationsByOverallDirect` or `associationsByOverallIndirect`.

Best,

Irene
