The first time you visit https://db.humanconnectome.org, you will need to register a new account. You can do this from the login / registration page
Activating your account
After you create your ConnectomeDB account, a confirmation email will be automatically sent to the email address that you specified for your account. You must click the confirmation link in that email in order to activate your account. If you did not receive that email, or you need to reactivate your account, you can request a new activation email by clicking the "Resend Verification Email" link on the login page.
Once your account is activated, you will be able to log in and see the list of studies and datasets in ConnectomeDB.
Data access and data use terms
Each study in ConnectomeDB can provide a set of data use terms which must be reviewed and accepted before a user can get access to that study's data. You can quickly review and accept these data use terms by clicking the "Data Use Terms Required" button related to the study you are interested in.
On the rare occasion that a study's data use terms were to change, each user would have to review and agree to the new terms before they can access that study's data on the site
Once the terms are accepted, buttons and selectors will appear in that study overview box that will allow you to explore and download HCP data by selecting options for groups of subjects.
Your login to ConnectomeDB times out every 30 minutes. Click the “renew” link in the top navigation bar to reset the timer as needed.

Once your ConnectomeDB account is set up and you have signed the HCP data use agreement, the header for the 1200 Subjects release will appear blue and on the right an “Open Dataset” button and two pulldowns for “Explore Subjects” and “Download Image Data” will be active.
If you click the “Download Images” or “Download CSV” buttons, only the subjects for which you filtered will be part of the data queued for download (see below).
You can also explore all the scan details and behavioral/individual difference data for any subject individually by clicking a Subject ID link from the list.
Now click the “Dataset Resources” button at the top right. This takes you to the WU-Minn HCP Dataset page (also accessible through the “Open Dataset” button on the Public Connectome Data splash page that you see when you first log in).
Here you see:
Buttons to Browse all Subjects, Open a set Group of Subjects in the dashboard (including any a user saves themselves), or Download Image data for the same set groups of subjects.
Links to Data Reference documents, online FAQs and individual difference/behavioral Data Dictionary.
Downloads of individual difference/behavioral data and expanded FreeSurfer anatomical measures
Links to HCP data processing software for MEG and MRI
Link to Order the complete dataset via “Connectome in a Box”
Downloads of 3T, 7T, and MEG tfMRI protocol E-Prime scripts
Links to Group Average rfMRI and tfMRI datasets
Link to the Netmats MegaTrawl analysis of correlations between imaging and non-imaging measures in the HCP data
Datasets designed for viewing in Connectome Workbench
If you have Restricted data access, you will see at the top left of the page is a pulldown to the right of “Current Project” that allows you to choose the level of data you want to view: Open Access, Restricted (contains fields that are potentially identifying), or Sensitive (contains fields potentially harmful or embarrassing to subjects). This pulldown persists throughout ConnectomeDB and, therefore, can be set from the Dashboard where data fields are viewed as well. More information on Access Levels is available at http://humanconnectome.org/study/hcp-young-adult/data-use-terms.
The default setting is Open Access. Restricted data view contains restricted data (Dashboard column headers in red) and all open access data. Sensitive data view contains sensitive data (Dashboard column headers in black) and restricted and open access data. When you select Restricted or Sensitive the area around the Current Project box is colored red to remind you that you are set to view restricted data.
The HCP built this access level setting into the user interface to allow investigators to control what kinds of data appear for different use case scenarios. For example, one can show only Open Access data when giving a lecture to a class, but view Sensitive data when filtering subjects by positive drug test results for a research study on drug use.
All downloads on ConnectomeDB require the Aspera browser plugin. If this plugin is not installed, ConnectomeDB will provide a link to install the latest version. There is no cost for using the Aspera browser plugin.
Installing the Aspera plugin to your browser requires you to restart your browser. Therefore, we recommend installing the plugin before you explore/select HCP data in ConnectomeDB.
In order to facilitate access to the very large data files generated on every subject, we have prepackaged data into convenient group data packages. Datasets can be downloaded from ConnectomeDB in set packages or users may order all the image data to be sent to them on hard drives.
Due to the large file sizes of the data, the HCP uses an Aspera server to dramatically boost data transfer speeds. Therefore, downloading data from the HCP requires you to have the Aspera plugin installed on your browser.
If you have not installed the plugin yet, a warning message will appear at the top of the browser window reminding you that you must Install the Aspera plugin before using any of ConnectomeDB's services, including downloading.
One common problem with installing Aspera on the Mac platform for non-US users is that you must add US English to the Languages list (using the checkbox) to your System Preferences>Personal>Language & Text settings.
If this is your first time downloading data from ConnectomeDB, before you start selecting packages to download, we highly recommend setting up the preferences in your Aspera Connect plugin to download to the appropriate place on your local or network hard drive. First time Aspera Setup Instructions.
Upon login to ConnectomeDB, you are brought to the Public Connectome Data splash page. If you choose one of the “Download Image Data” options (e.g. 7T Subjects) in the pulldown at the top right of the WU-Minn HCP Data-1200 Subjects section, you will launch the Download Packages page.
Using the menus in the left column, select the following attributes of the data you want to download.
To make selections for download, click the “add to queue” icon to the left of each dataset package.
The total size of the data you have queued for download is at the upper and bottom right. Use this calculation to check against your available hard drive space.
When you are done making your selections, click the Download Packages button at the upper or lower right. A popup will remind you again what packages you selected and the total size of the files. Clicking “Download Now” will automatically open Aspera Connect and launch the download.
If you have not setup Aspera Connect, as described above, by default the data will start downloading to your Desktop (!!).
You can stop any download by clicking the “X” button to the right of the download progress bar.
If the download does not start automatically, use the link on the Download Package Launcher page in your browser to restart. Once started, the blue bar in the Aspera Connect: Transfers window will show your download progress (per subject file, not overall progress).
Of course, the more subjects and packages you selected for download, the longer your download will take (remember, this is big data!). This is why we offer the “Connectome in a Box” and Amazon S3 options for those who want data on many subjects.
If you have trouble with getting Aspera downloads to work on your network, please consult these troubleshooting steps: Aspera Plugin: Help and FAQ.
Now that you have downloaded the data you want, here’s some tips for handling the data:
If you distribute HCP data in any way, all users (those who access HCP data) must register at ConnectomeDB and sign the Open Access Data Use Terms in order to comply with regulations on human subjects research.
