We are happy to discuss capabilities of the IDA and learn more about your data repository needs. Please contact us to find out more: . Click here to copy the email address.

• For open-sharing studies, only an IDA user account (free) is needed; these studies display an [OPEN USE] label in the Featured Studies section.
• For restricted-sharing studies, access permission may be requested by submitting a data use application (free); these studies display a green [APPLY] button.

The IDA contains data collected for a continuously growing number of research studies and clinical trials including studies of normal development, neurodegenerative diseases and brain injury. Access to the IDA allows you to search and download data (data access approval required - see How do I obtain access to data stored in the IDA).

More than 150 organizations use the IDA globally, and the IDA infrastructure has contributed to over 4,000 scientific articles.

To register an account go to ida.loni.usc.edu and click the 'Instant free signup' button.

You will need to register for a new IDA account using an email address that you can access.

Yes, you can add a co-investigator by logging in and going to the 'My Account' page. From there you can select the study you have access to and then add a co-investigator.

You can cancel your access to an IDA study by logging in and going to the 'My Account' page. From there you can select the study you no longer need to access and cancel.

The 1-Click download option is set up to download all data in one zip file, when possible. The Advanced download option allows you to group your download into multiple zip files and also to download a list of those URLs to be used with a Download Manager.

Software applications known as Download Managers may help you manage your IDA file downloads: they can automate downloads of multiple files and can keep track of large files seamlessly while you do other things or are away from your computer. A major advantage of most Download Managers is that if a download is briefly interrupted due to poor connectivity, that download will continue from the point where it was interrupted instead of restarting from the beginning. Note: IDA does not endorse or support any Download Managers and is not responsible for download errors or subsequent issues resulting from use of any third-party products. However, IDA has tested and suggests the following free products for your consideration: jDownloader, Uget, FDM.

We suggest using Firefox which automatically tries to restart the download if a network interruption occurs. We also suggest limiting the number of large files you attempt to simultaneously download.

Downloads must be started and completed on the same computer and IP address used to log into the IDA and sessions time out after a period of inactivity. If your session expired due to inactivity, you will need to log back in and restart your download. Ensure that your IP address is static and if not, we suggest that users work with their IT department to establish a static IP address. If you are still experiencing issues, please contact us at .

Zip files will be downloaded in Zip64 format. If you are experiencing issues unzipping your files make sure your decompressor is able to unzip Zip64 files. If you are using Safari, before downloading the Zip file make sure “ Open ‘safe’ files after downloading ” is unchecked in your Safari General Preferences. Leaving this checked may result in issues when unzipping downloaded files.

You must first search for images using one of the search options and then from the search results page select and add the desired images to a new or existing collection. Refer to the IDA manual for the detailed steps on this process.

Although some studies have chosen to create collections shared with all approved users, at present there is no way to share user collections with specific individuals.

You can delete a collection by opening a collection, selecting 'All' items in the collection and then clicking 'Remove'.

Only authorized users of a study are given upload access. You will need to register for an IDA account and then email to obtain the access, including the specific details required by the study (generally in the study technical manual provided by the study coordinator).

First select the project you need to upload to from the PROJECTS menu. The Archive menu will appear if you have been granted upload access for the study.

It is possible to upload to IDA either from the browser or by downloading the IDA-Uploader application. For both methods a computer with access to the internet is required. For the requirements specific to each method please refer to the IDA manual.

The IDA Web Uploader buttons are only compatible with the Internet Explorer(IE) web browser (minimum version 9) and java plug-in (minimum version 1.8, 32 bit). If you no longer have access to this version, we suggest you install the IDA-Uploader Application. Refer to the IDA manual for detailed steps on this process.
