I need to download lots of structural T1w MR images from ADNI for a project of mine.
I definitely remember it was possible to donwload a csv file with a QC rating for each scan. There's even a dedicated webpage for that. 
I can't find this column anymore to save my life!

In the data dictionary file, I see that there used to be columns named "Study Quality Assessment", "Series Quality Assessment" and "Deface status". 
Now they're all indicated as "redacted" and "administrative columns redacted". 

Am I understanding correctly? Where is the QC indicated now?
Thank you
Luca
