You can search the database to produce a list of subjects with 100% completion of diffusion scans. 180 directions was the minimum that was released and means that they did not manage to complete all 6 scans, but only completed 4.

Is there a list documenting who did not finish the diffusion scan? So far I found around 90 subjects having this problem, and most of them have only 180 directions.
