What (maybe home-based) useful new research could be done using the DecodeME cohort?

I think that any continuation would need to think of how to keep those flagship aspects/that control and transparency/privacy etc in place

Yep, absolutely. The PI would still be the lead, though, and would need to write it up at the end anyway. I imagine that would be covered by the original grant, as it's a big job that gobbles up a lot of time.
