Question Posted 03/03/22:
I would like to use the ADNI MRI images for my research project. I have been facing an issue in terms of downloading any image data from ADNI. My user account is currently activated using this email address. Whenever I try to download any image data in "Archive" or "Nifiti" or "1-click download" or "Advance Download" way, an HTTP 403 Error code is shown delineating "Access Denied". However, I was able to download a single MRI image as Archive once 2 weeks ago. But after that, for the last 2 weeks, I have been repeatedly trying to download images in many ways and failed each time with an HTTP 403 error. I have tried to download using different browsers like Google Chrome, Mozilla Firefox, Microsoft Edge and also using different other devices. Yet, the issue is not solved.

I would like to request you to help me to solve this issue by taking necessary actions as soon as possible.

Please ensure that the images are being downloaded from the same computer in which the collection was created.
Other issues could be that the URL expired or a dynamic IP address.
If it is a dynamic IP issue, we suggest that users work with their IT department to establish a static IP address.
