Well, the heading says it all:
what gets submitted to CASP?
A 3D structure of the one top player?
The prediction of all participants?
A simple text file of the result from the Top 10 people?
Madde keeps a page detailing progress in CASP 11 here http://de.foldit.wikia.com/wiki/CASP11
It includes solutions submitted by groups and sometimes, but not always, solutions submitted by FoldIt
For targets with WeFold-puzzles only there are no models submitted by Foldit, because - unlike the groups - Foldit doesn't have one specific WeFold-CASP-Team. Foldit will instead "pass all WeFold Foldit solutions further down the WeFold pipeline" for several wf-teams and then they will submit them.
Tx Madde: I was wondering why some puzzles didn't include FoldIt submissions.
